+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+\`configure' configures asio 1.28.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.

+      Asio now provides the interfaces and functionality specified by the "C++
+      Extensions for Networking" Technical Specification. In addition to access
+      via the usual Asio header files, this functionality may be accessed through
+      special headers that correspond to the header files defined in the TS. These
+      are listed in the table below:

+        Asio may be used to perform both synchronous and asynchronous operations
+        on I/O objects such as sockets. Before using Asio it may be useful to get
+        a conceptual picture of the various parts of Asio, your program, and how
+        they work together.
+      </p>
+<p>
+        As an introductory example, let's consider what happens when you perform
+        a connect operation on a socket. We shall start by examining synchronous
+        operations.

+        object, <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">thread_pool</span></code> object, or <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">system_context</span></code>.
+        This <span class="bold"><strong>I/O execution context</strong></span> represents <span class="bold"><strong>your program</strong></span>'s link to the <span class="bold"><strong>operating
+        system</strong></span>'s I/O services.
+      </p>
+<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">io_context</span> <span class="identifier">io_context</span><span class="special">;</span>
+</pre>
+<p>
+        To perform I/O operations <span class="bold"><strong>your program</strong></span> will
+        need an <span class="bold"><strong>I/O object</strong></span> such as a TCP socket:
+      </p>
+<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span> <span class="identifier">socket</span><span class="special">(</span><span class="identifier">io_context</span><span class="special">);</span>
+</pre>
+<p>
+        When a synchronous connect operation is performed, the following sequence
+        of events occurs:
+      </p>
+<p>
+        1. <span class="bold"><strong>Your program</strong></span> initiates the connect operation
+        by calling the <span class="bold"><strong>I/O object</strong></span>:
+      </p>
+<pre class="programlisting"><span class="identifier">socket</span><span class="special">.</span><span class="identifier">connect</span><span class="special">(</span><span class="identifier">server_endpoint</span><span class="special">);</span>
+</pre>
+<p>
+        2. The <span class="bold"><strong>I/O object</strong></span> forwards the request to
+        the <span class="bold"><strong>I/O execution context</strong></span>.
+      </p>
+<p>
+        3. The <span class="bold"><strong>I/O execution context</strong></span> calls on the
+        <span class="bold"><strong>operating system</strong></span> to perform the connect
+        operation.
+      </p>
+<p>
+        4. The <span class="bold"><strong>operating system</strong></span> returns the result
+        of the operation to the <span class="bold"><strong>I/O execution context</strong></span>.
+      </p>
+<p>
+        5. The <span class="bold"><strong>I/O execution context</strong></span> translates
+        any error resulting from the operation into an object of type <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span></code>. An <code class="computeroutput"><span class="identifier">error_code</span></code>
+        may be compared with specific values, or tested as a boolean (where a <code class="computeroutput"><span class="keyword">false</span></code> result means that no error occurred).
+        The result is then forwarded back up to the <span class="bold"><strong>I/O object</strong></span>.
+      </p>
+<p>
+        6. The <span class="bold"><strong>I/O object</strong></span> throws an exception of
+        type <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">system_error</span></code> if the operation failed. If
+        the code to initiate the operation had instead been written as:
+      </p>
+<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span> <span class="identifier">ec</span><span class="special">;</span>
+<span class="identifier">socket</span><span class="special">.</span><span class="identifier">connect</span><span class="special">(</span><span class="identifier">server_endpoint</span><span class="special">,</span> <span class="identifier">ec</span><span class="special">);</span>
+</pre>
+<p>
+        then the <code class="computeroutput"><span class="identifier">error_code</span></code> variable
+        <code class="computeroutput"><span class="identifier">ec</span></code> would be set to the result
+        of the operation, and no exception would be thrown.
+      </p>
+<p>
+        When an asynchronous operation is used, a different sequence of events occurs.
+      </p>
+<p>
+        <span class="inlinemediaobject"><img src="../../async_op1.png"></span>
+      </p>
+<p>
+        1. <span class="bold"><strong>Your program</strong></span> initiates the connect operation
+        by calling the <span class="bold"><strong>I/O object</strong></span>:
+      </p>
+<pre class="programlisting"><span class="identifier">socket</span><span class="special">.</span><span class="identifier">async_connect</span><span class="special">(</span><span class="identifier">server_endpoint</span><span class="special">,</span> <span class="identifier">your_completion_handler</span><span class="special">);</span>
+</pre>
+<p>
+        where <code class="computeroutput"><span class="identifier">your_completion_handler</span></code>
+        is a function or function object with the signature:
+      </p>
+<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">your_completion_handler</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span><span class="special">&amp;</span> <span class="identifier">ec</span><span class="special">);</span>
+</pre>
+<p>
+        The exact signature required depends on the asynchronous operation being
+        performed. The reference documentation indicates the appropriate form for
+        each operation.
+      </p>
+<p>
+        2. The <span class="bold"><strong>I/O object</strong></span> forwards the request to
+        the <span class="bold"><strong>I/O execution context</strong></span>.
+      </p>
+<p>
+        3. The <span class="bold"><strong>I/O execution context</strong></span> signals to
+        the <span class="bold"><strong>operating system</strong></span> that it should start
+        an asynchronous connect.
+      </p>
+<p>
+        Time passes. (In the synchronous case this wait would have been contained
+        entirely within the duration of the connect operation.)
+      </p>
+<p>
+        <span class="inlinemediaobject"><img src="../../async_op2.png"></span>
+      </p>
+<p>
+        4. The <span class="bold"><strong>operating system</strong></span> indicates that the
+        connect operation has completed by placing the result on a queue, ready to
+        be picked up by the <span class="bold"><strong>I/O execution context</strong></span>.
+      </p>
+<p>
+        5. When using an <code class="computeroutput"><span class="identifier">io_context</span></code>
+        as the <span class="bold"><strong>I/O execution context</strong></span>, <span class="bold"><strong>your program</strong></span> must make a call to <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code>
+        (or to one of the similar <code class="computeroutput"><span class="identifier">io_context</span></code>
+        member functions) in order for the result to be retrieved. A call to <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code> blocks
+        while there are unfinished asynchronous operations, so you would typically
+        call it as soon as you have started your first asynchronous operation.
+      </p>
+<p>
+        6. While inside the call to <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code>,
+        the <span class="bold"><strong>I/O execution context</strong></span> dequeues the result
+        of the operation, translates it into an <code class="computeroutput"><span class="identifier">error_code</span></code>,
+        and then passes it to <span class="bold"><strong>your completion handler</strong></span>.
+      </p>
+<p>
+        This is a simplified picture of how Asio operates. You will want to delve
+        further into the documentation if your needs are more advanced, such as extending
+        Asio to perform other types of asynchronous operations.

+<p>
+          Every coroutine needs to have its own executor. Since the coroutine gets
+          called multiple times, it cannot take the executor from the caller like
+          an <code class="computeroutput"><span class="identifier">awaitable</span></code>. Therefore
+          a <code class="computeroutput"><span class="identifier">coro</span></code> requires to get
+          an executor or an execution_context passed in as the first parameter.

+</pre>
+<p>
+          It is to note, that an execution_context is defined as loosely as possible.
+          An execution context is any object that has a <code class="computeroutput"><span class="identifier">get_executor</span><span class="special">()</span></code> function, which returns an executor that
+          can be transformed into the executor_type of the coroutine. This allows
+          most io_objects to be used as the source of the executor:
+        </p>
+<pre class="programlisting"><span class="identifier">coro</span><span class="special">&lt;</span><span class="keyword">int</span><span class="special">&gt;</span> <span class="identifier">with_socket</span><span class="special">(</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span><span class="special">);</span>
+</pre>
+<p>
+          Additionally, a <code class="computeroutput"><span class="identifier">coro</span></code> that
+          is a member function will check the <code class="computeroutput"><span class="keyword">this</span></code>
+          pointer as well, either if it's an executor or an execution context:
+        </p>
+<pre class="programlisting"><span class="keyword">struct</span> <span class="identifier">my_io_object</span>

+</pre>
+<p>
+          Finally, a member coro can be given an explicit executor or execution context,
+          to override the one of the object:

+<p>
+          The first argument to <code class="computeroutput"><span class="identifier">co_spawn</span><span class="special">()</span></code> is an <a class="link" href="../../reference/Executor1.html" title="Executor requirements">executor</a>
+          that determines the context in which the coroutine is permitted to execute.
+          For example, a server's per-client object may consist of multiple coroutines;
+          they should all run on the same <code class="computeroutput"><span class="identifier">strand</span></code>
+          so that no explicit synchronisation is required.
+        </p>
+<p>
+          The second argument is an <a class="link" href="../../reference/awaitable.html" title="awaitable"><code class="computeroutput"><span class="identifier">awaitable</span><span class="special">&lt;</span><span class="identifier">R</span><span class="special">&gt;</span></code></a>,
+          that is the result of the coroutine's entry point function, and in the
+          above example is the result of the call to <code class="computeroutput"><span class="identifier">echo</span></code>.
+          (Alternatively, this argument can be a function object that returns the
+          <a class="link" href="../../reference/awaitable.html" title="awaitable"><code class="computeroutput"><span class="identifier">awaitable</span><span class="special">&lt;</span><span class="identifier">R</span><span class="special">&gt;</span></code></a>.) The template parameter <code class="computeroutput"><span class="identifier">R</span></code> is the type of return value produced
+          by the coroutine. In the above example, the coroutine returns <code class="computeroutput"><span class="keyword">void</span></code>.
+        </p>
+<p>
+          The third argument is a completion token, and this is used by <code class="computeroutput"><span class="identifier">co_spawn</span><span class="special">()</span></code>
+          to produce a completion handler with signature <code class="computeroutput"><span class="keyword">void</span><span class="special">(</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">exception_ptr</span><span class="special">,</span> <span class="identifier">R</span><span class="special">)</span></code>.
+          This completion handler is invoked with the result of the coroutine once
+          it has finished. In the above example we pass a completion token type,
+          <a class="link" href="../../reference/detached.html" title="detached"><code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">detached</span></code></a>,
+          which is used to explicitly ignore the result of an asynchronous operation.
+        </p>
+<p>
+          In this example the body of the coroutine is implemented in the <code class="computeroutput"><span class="identifier">echo</span></code> function. When the <code class="computeroutput"><span class="identifier">use_awaitable</span></code> completion token is passed
+          to an asynchronous operation, the operation's initiating function returns
+          an <code class="computeroutput"><span class="identifier">awaitable</span></code> that may be
+          used with the <code class="computeroutput"><span class="identifier">co_await</span></code>
+          keyword:
+        </p>
+<pre class="programlisting"><span class="identifier">std</span><span class="special">::</span><span class="identifier">size_t</span> <span class="identifier">n</span> <span class="special">=</span> <span class="identifier">co_await</span> <span class="identifier">socket</span><span class="special">.</span><span class="identifier">async_read_some</span><span class="special">(</span><span class="identifier">asio</span><span class="special">::</span><span class="identifier">buffer</span><span class="special">(</span><span class="identifier">data</span><span class="special">),</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">use_awaitable</span><span class="special">);</span>
+</pre>
+<p>
+          Where an asynchronous operation's handler signature has the form:
+        </p>
+<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">handler</span><span class="special">(</span><span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span> <span class="identifier">ec</span><span class="special">,</span> <span class="identifier">result_type</span> <span class="identifier">result</span><span class="special">);</span>
+</pre>
+<p>
+          the resulting type of the <code class="computeroutput"><span class="identifier">co_await</span></code>
+          expression is <code class="computeroutput"><span class="identifier">result_type</span></code>.
+          In the <code class="computeroutput"><span class="identifier">async_read_some</span></code>
+          example above, this is <code class="computeroutput"><span class="identifier">size_t</span></code>.
+          If the asynchronous operation fails, the <code class="computeroutput"><span class="identifier">error_code</span></code>
+          is converted into a <code class="computeroutput"><span class="identifier">system_error</span></code>
+          exception and thrown.
+        </p>
+<p>
+          Where a handler signature has the form:
+        </p>
+<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">handler</span><span class="special">(</span><span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span> <span class="identifier">ec</span><span class="special">);</span>
+</pre>
+<p>
+          the <code class="computeroutput"><span class="identifier">co_await</span></code> expression
+          produces a <code class="computeroutput"><span class="keyword">void</span></code> result. As
+          above, an error is passed back to the coroutine as a <code class="computeroutput"><span class="identifier">system_error</span></code>
+          exception.

+          The <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">use_future</span></code> completion token provides
+          first-class support for returning a <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">future</span></code>
+          from an asynchronous operation's initiating function.
+        </p>
+<p>
+          To use <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">use_future</span></code>, pass it to an asynchronous
+          operation instead of a completion handler. For example:

+</pre>
+<p>
+          the initiating function returns a <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">future</span></code>
+          templated on <code class="computeroutput"><span class="identifier">result_type</span></code>.
+          In the above example, this is <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">size_t</span></code>.
+          If the asynchronous operation fails, the <code class="computeroutput"><span class="identifier">error_code</span></code>
+          is converted into a <code class="computeroutput"><span class="identifier">system_error</span></code>
+          exception and passed back to the caller through the future.

+<p>
+          The <code class="computeroutput"><span class="identifier">associated_immediate_executor</span></code>
+          associator trait, along with the <code class="computeroutput"><span class="identifier">bind_immediate_executor</span></code>
+          function, provide the ability to customise the execution of a completion
+          handler when an asynchronous operation completes immediately.
+        </p>
+<p>
+          When a supported operation completes immediately (that is, within the initiating
+          function) the associated immmediate executor is obtained, and the completion
+          handler is delivered through that executor as if by using <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">dispatch</span></code> on that executor. By default,
+          the immediate executor delivers the completion handler as if using <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">post</span></code> via the operation's I/O executor.
+        </p>
+<p>
+          For example, to allow a recursive call to the completion handler of an
+          <code class="computeroutput"><span class="identifier">async_read_some</span></code> operation,
+          we may specify that immediate completion is delivered via a <code class="computeroutput"><span class="identifier">system_executor</span></code>:
+        </p>
+<pre class="programlisting"><span class="identifier">my_socket</span><span class="special">.</span><span class="identifier">async_read_some</span><span class="special">(</span><span class="identifier">my_buffer</span><span class="special">,</span>
+    <span class="identifier">bind_immediate_executor</span><span class="special">(</span>

+    <span class="special">)</span>
+  <span class="special">);</span>
+</pre>
+<p>
+          Immediate execution is currently supported for asynchronous operations
+          on reactor-based sockets and descriptors, and for asynchronous operations
+          on channels.
+        </p>
+<p>
+          <span class="bold"><strong>Note:</strong></span> When enabling the immediate execution
+          of completion handlers, care must be taken to ensure that unbounded recursion
+          and stack overflow do not occur. Furthermore, use of immediate completion
+          may impact the fairness of completion handler scheduling, with a potential
+          for starvation for other pending work.

+          The first argument to <code class="computeroutput"><span class="identifier">spawn</span><span class="special">()</span></code> may be an executor or execution context.
+          This argument determines the context in which the coroutine is permitted
+          to execute. For example, a server's per-client object may consist of multiple
+          coroutines; they should all run on the same <code class="computeroutput"><span class="identifier">strand</span></code>
+          so that no explicit synchronisation is required.
+        </p>
+<p>
+          The second argument is a function object with signature:

+          is converted into a <code class="computeroutput"><span class="identifier">system_error</span></code>
+          exception and thrown.

+          The <code class="computeroutput"><span class="identifier">any_completion_handler</span><span class="special">&lt;&gt;</span></code> class template can be used to type-erase
+          completion handlers. This template stores a completion handler in a runtime-polymorphic
+          wrapper, and forwards the function call operator, associated executor,
+          associated allocator, and associated cancellation slot to the target handler.
+        </p>
+<p>
+          One use case is to enable separate compilation of asynchronous operation
+          implementations. For example, we can declare our implementation function
+          in a header file, and provide a thin asynchronous operation wrapper:

+<p>
+          Many asynchronous operations need to allocate an object to store state
+          associated with the operation. For example, a Win32 implementation needs
+          <code class="computeroutput"><span class="identifier">OVERLAPPED</span></code>-derived objects
+          to pass to Win32 API functions.
+        </p>
+<p>
+          Furthermore, programs typically contain easily identifiable chains of asynchronous
+          operations. A half duplex protocol implementation (e.g. an HTTP server)
+          would have a single chain of operations per client (receives followed by
+          sends). A full duplex protocol implementation would have two chains executing
+          in parallel. Programs should be able to leverage this knowledge to reuse
+          memory for all asynchronous operations in a chain.
+        </p>
+<p>
+          Given a copy of a user-defined <code class="computeroutput"><span class="identifier">Handler</span></code>
+          object <code class="computeroutput"><span class="identifier">h</span></code>, if the implementation
+          needs to allocate memory associated with that handler it will obtain an
+          allocator using the <code class="computeroutput"><span class="identifier">get_associated_allocator</span></code>
+          function. For example:
+        </p>
+<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">associated_allocator_t</span><span class="special">&lt;</span><span class="identifier">Handler</span><span class="special">&gt;</span> <span class="identifier">a</span> <span class="special">=</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">get_associated_allocator</span><span class="special">(</span><span class="identifier">h</span><span class="special">);</span>
+</pre>
+<p>
+          The associated allocator must satisfy the standard Allocator requirements.
+        </p>
+<p>
+          By default, handlers use the standard allocator (which is implemented in
+          terms of <code class="computeroutput"><span class="special">::</span><span class="keyword">operator</span>
+          <span class="keyword">new</span><span class="special">()</span></code>

+          The allocator may be customised for a particular handler type by specifying

+          and member function <code class="computeroutput"><span class="identifier">get_allocator</span><span class="special">()</span></code>:

+          The implementation guarantees that the deallocation will occur before the
+          associated handler is invoked, which means the memory is ready to be reused
+          for any new asynchronous operations started by the handler.
+        </p>
+<p>
+          The custom memory allocation functions may be called from any user-created
+          thread that is calling an Asio library function. The implementation guarantees,
+          for the asynchronous operations included with the library, that within
+          the context of an individual operation the implementation will not make
+          concurrent calls to the memory allocation functions for that handler. The
+          implementation will insert appropriate memory barriers to ensure correct
+          memory visibility should an asynchronous operation need to call the allocation
+          functions from different threads. (Note: If the same allocator is shared
+          across multiple concurrent asynchronous operations, this can result in
+          concurrent calls to the memory allocation functions. Use of a <a class="link" href="strands.html" title="Strands: Use Threads Without Explicit Locking">strand</a>
+          does not prevent these concurrent calls, as an operation may need to allocate
+          memory from outside the strand. In this case, the shared allocator is responsible
+          for providing the necessary thread safety guarantees.)

+<p>
+          Fundamentally, I/O involves the transfer of data to and from contiguous
+          regions of memory, called buffers. These buffers can be simply expressed
+          as a tuple consisting of a pointer and a size in bytes. However, to allow
+          the development of efficient network applications, Asio includes support
+          for scatter-gather operations. These operations involve one or more buffers:
+        </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+              A scatter-read receives data into multiple buffers.
+            </li>
+<li class="listitem">
+              A gather-write transmits multiple buffers.
+            </li>
+</ul></div>
+<p>
+          Therefore we require an abstraction to represent a collection of buffers.
+          The approach used in Asio is to define a type (actually two types) to represent
+          a single buffer. These can be stored in a container, which may be passed
+          to the scatter-gather operations.
+        </p>
+<p>
+          In addition to specifying buffers as a pointer and size in bytes, Asio
+          makes a distinction between modifiable memory (called mutable) and non-modifiable
+          memory (where the latter is created from the storage for a const-qualified
+          variable). These two types could therefore be defined as follows:
+        </p>
+<pre class="programlisting"><span class="keyword">typedef</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">pair</span><span class="special">&lt;</span><span class="keyword">void</span><span class="special">*,</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">size_t</span><span class="special">&gt;</span> <span class="identifier">mutable_buffer</span><span class="special">;</span>

+</pre>
+<p>
+          Here, a mutable_buffer would be convertible to a const_buffer, but conversion
+          in the opposite direction is not valid.
+        </p>
+<p>
+          However, Asio does not use the above definitions as-is, but instead defines
+          two classes: <code class="computeroutput"><span class="identifier">mutable_buffer</span></code>
+          and <code class="computeroutput"><span class="identifier">const_buffer</span></code>. The goal
+          of these is to provide an opaque representation of contiguous memory, where:
+        </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+              Types behave as std::pair would in conversions. That is, a <code class="computeroutput"><span class="identifier">mutable_buffer</span></code> is convertible to
+              a <code class="computeroutput"><span class="identifier">const_buffer</span></code>, but
+              the opposite conversion is disallowed.
+            </li>
+<li class="listitem">
+              There is protection against buffer overruns. Given a buffer instance,
+              a user can only create another buffer representing the same range of
+              memory or a sub-range of it. To provide further safety, the library
+              also includes mechanisms for automatically determining the size of
+              a buffer from an array, <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">array</span></code>
+              or <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span></code> of POD elements, or from a
+              <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>.

+              this, but it is required by the library implementation to pass the
+              raw memory to the underlying operating system functions.
+            </li>
+</ul></div>
+<p>
+          Finally, multiple buffers can be passed to scatter-gather operations (such

+          by putting the buffer objects into a container. The <code class="computeroutput"><span class="identifier">MutableBufferSequence</span></code>
+          and <code class="computeroutput"><span class="identifier">ConstBufferSequence</span></code>
+          concepts have been defined so that containers such as <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span></code>,

+          Asio takes advantage of this feature to add buffer debugging. Consider
+          the following code:
+        </p>
+<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">dont_do_this</span><span class="special">()</span>
+<span class="special">{</span>
+ <span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span> <span class="identifier">msg</span> <span class="special">=</span> <span class="string">"Hello, world!"</span><span class="special">;</span>
+ <span class="identifier">asio</span><span class="special">::</span><span class="identifier">async_write</span><span class="special">(</span><span class="identifier">sock</span><span class="special">,</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">buffer</span><span class="special">(</span><span class="identifier">msg</span><span class="special">),</span> <span class="identifier">my_handler</span><span class="special">);</span>
+<span class="special">}</span>
+</pre>
+<p>
+          When you call an asynchronous read or write you need to ensure that the
+          buffers for the operation are valid until the completion handler is called.
+          In the above example, the buffer is the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
+          variable <code class="computeroutput"><span class="identifier">msg</span></code>. This variable
+          is on the stack, and so it goes out of scope before the asynchronous operation
+          completes. If you're lucky then the application will crash, but random
+          failures are more likely.
+        </p>
+<p>
+          When buffer debugging is enabled, Asio stores an iterator into the string
+          until the asynchronous operation completes, and then dereferences it to
+          check its validity. In the above example you would observe an assertion
+          failure just before Asio tries to call the completion handler.
+        </p>
+<p>
+          This feature is automatically made available for Microsoft Visual Studio
+          8.0 or later and for GCC when <code class="computeroutput"><span class="identifier">_GLIBCXX_DEBUG</span></code>
+          is defined. There is a performance cost to this checking, so buffer debugging
+          is only enabled in debug builds. For other compilers it may be enabled
+          by defining <code class="computeroutput"><span class="identifier">ASIO_ENABLE_BUFFER_DEBUGGING</span></code>.
+          It can also be explicitly disabled by defining <code class="computeroutput"><span class="identifier">ASIO_DISABLE_BUFFER_DEBUGGING</span></code>.

+            These type requirements and classes are the low level building blocks

+          I/O objects, such as sockets and timers, support object-wide cancellation
+          of outstanding asynchronous operations via their <code class="computeroutput"><span class="identifier">close</span></code>
+          or <code class="computeroutput"><span class="identifier">cancel</span></code> member functions.
+          However, certain asynchronous operations also support individual, targeted
+          cancellation. This per-operation cancellation is enabled by specifying
+          that a completion handler has an <a class="link" href="../../reference/associated_cancellation_slot.html" title="associated_cancellation_slot">associated
+          cancellation slot</a> which satisfies the <a class="link" href="../../reference/CancellationSlot.html" title="Cancellation slot requirements">CancellationSlot</a>

+          delivering a cancellation request.

+          Given a copy of a user-defined <code class="computeroutput"><span class="identifier">Handler</span></code>
+          object <code class="computeroutput"><span class="identifier">h</span></code>, if an asynchronous
+          operation supports cancellation it will obtain a cancellation slot using
+          the <code class="computeroutput"><span class="identifier">get_associated_cancellation_slot</span></code>
+          function. For example:
+        </p>

+<p>
+          The associated cancellation slot must satisfy the CancellationSlot type
+          requirements.
+        </p>

+          By default, handlers use a default-constructed <a class="link" href="../../reference/cancellation_slot.html" title="cancellation_slot"><code class="computeroutput"><span class="identifier">cancellation_slot</span></code></a>, which means
+          that per-operation cancellation is disabled. The cancellation slot may
+          be customised for a particular handler type by specifying a nested type
+          <code class="computeroutput"><span class="identifier">cancellation_slot_type</span></code>

+          A <code class="computeroutput"><span class="identifier">cancellation_signal</span></code> contains
+          a single slot, and consequently a cancellation signal/slot pair may be
+          used with at most one operation at a time. However, the same slot may be
+          reused for subsequent operations.
+        </p>
+<p>
+          To support cancellation, an asynchronous operation installs a cancellation
+          handler into the slot by calling the slot's <code class="computeroutput"><span class="identifier">assign</span></code>
+          or <code class="computeroutput"><span class="identifier">emplace</span></code> functions. This
+          handler will be invoked when a cancellation signal is emitted. A slot holds

+          any previously installed handler.

+<p>
+          When emitting a cancellation signal, the caller must specify a <a class="link" href="../../reference/cancellation_type.html" title="cancellation_type">cancellation

+          For example, if application logic requires that an operation complete with
+          all-or-nothing side effects, it should emit only the <code class="computeroutput"><span class="identifier">total</span></code>
+          cancellation type. If this type is unsupported by the target operation,
+          no cancellation will occur.
+        </p>
+<p>
+          Furthermore, a stronger guarantee always satisfies the requirements of
+          a weaker guarantee. The <code class="computeroutput"><span class="identifier">partial</span></code>
+          guarantee still satisfies the <code class="computeroutput"><span class="identifier">terminal</span></code>
+          guarantee. The <code class="computeroutput"><span class="identifier">total</span></code> guarantee
+          satisfies both <code class="computeroutput"><span class="identifier">partial</span></code>
+          and <code class="computeroutput"><span class="identifier">total</span></code>. This means that
+          when an operation supports a given cancellation type as its strongest guarantee,
+          it should honour cancellation requests for any of the weaker guarantees.
+        </p>
+<p>
+          Cancellation requests should not be emitted during an asynchronous operation's
+          initiating function. Cancellation requests that are emitted before an operation
+          starts have no effect. Similarly, cancellation requests made after completion
+          have no effect.
+        </p>
+<p>
+          When emitting a cancellation signal, the thread safety rules apply as if
+          calling a member function on the target operation's I/O object. For non-composed
+          operations, this means that it is safe to emit the cancellation signal
+          from any thread provided there are no other concurrent calls to the I/O
+          object, and no other concurrent cancellation signal requests. For composed
+          operations, care must be taken to ensure the cancellation request does
+          not occur concurrently with the operation's intermediate completion handlers.

+<p>
+          To aid in debugging asynchronous programs, Asio provides support for handler
+          tracking. When enabled by defining <code class="computeroutput"><span class="identifier">ASIO_ENABLE_HANDLER_TRACKING</span></code>,
+          Asio writes debugging output to the standard error stream. The output records
+          asynchronous operations and the relationships between their handlers.
+        </p>
+<p>
+          This feature is useful when debugging and you need to know how your asynchronous
+          operations are chained together, or what the pending asynchronous operations
+          are. As an illustration, here is the output when you run the HTTP Server
+          example, handle a single request, then shut down via Ctrl+C:

+          Many commonly-used internet protocols are line-based, which means that
+          they have protocol elements that are delimited by the character sequence
+          <code class="computeroutput"><span class="string">"\r\n"</span></code>. Examples
+          include HTTP, SMTP and FTP. To more easily permit the implementation of
+          line-based protocols, as well as other protocols that use delimiters, Asio
+          includes the functions <code class="computeroutput"><span class="identifier">read_until</span><span class="special">()</span></code> and <code class="computeroutput"><span class="identifier">async_read_until</span><span class="special">()</span></code>.
+        </p>

+          The following example illustrates the use of <code class="computeroutput"><span class="identifier">async_read_until</span><span class="special">()</span></code> in an HTTP server, to receive the first

+<p>
+          Sometimes a program must be integrated with a third-party library that
+          wants to perform the I/O operations itself. To facilitate this, Asio includes
+          synchronous and asynchronous operations that may be used to wait for a
+          socket to become ready to read, ready to write, or to have a pending error
+          condition.
+        </p>
+<p>
+          As an example, to perform a non-blocking read something like the following
+          may be used:
+        </p>

+<p>
+          A strand is defined as a strictly sequential invocation of event handlers
+          (i.e. no concurrent invocation). Use of strands allows execution of code
+          in a multithreaded program without the need for explicit locking (e.g.
+          using mutexes).
+        </p>
+<p>
+          Strands may be either implicit or explicit, as illustrated by the following
+          alternative approaches:
+        </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+              Calling io_context::run() from only one thread means all event handlers
+              execute in an implicit strand, due to the io_context's guarantee that
+              handlers are only invoked from inside run().
+            </li>
+<li class="listitem">
+              Where there is a single chain of asynchronous operations associated
+              with a connection (e.g. in a half duplex protocol implementation like
+              HTTP) there is no possibility of concurrent execution of the handlers.
+              This is an implicit strand.
+            </li>
+<li class="listitem">
+              An explicit strand is an instance of <code class="computeroutput"><span class="identifier">strand</span><span class="special">&lt;&gt;</span></code> or <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">strand</span></code>.
+              All event handler function objects need to be bound to the strand using
+              <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">bind_executor</span><span class="special">()</span></code>
+              or otherwise posted/dispatched through the strand object.
+            </li>
+</ul></div>
+<p>
+          In the case of composed asynchronous operations, such as <code class="computeroutput"><span class="identifier">async_read</span><span class="special">()</span></code>
+          or <code class="computeroutput"><span class="identifier">async_read_until</span><span class="special">()</span></code>,
+          if a completion handler goes through a strand, then all intermediate handlers
+          should also go through the same strand. This is needed to ensure thread
+          safe access for any objects that are shared between the caller and the
+          composed operation (in the case of <code class="computeroutput"><span class="identifier">async_read</span><span class="special">()</span></code> it's the socket, which the caller can
+          <code class="computeroutput"><span class="identifier">close</span><span class="special">()</span></code>
+          to cancel the operation).
+        </p>
+<p>
+          To achieve this, all asynchronous operations obtain the handler's associated
+          executor by using the <code class="computeroutput"><span class="identifier">get_associated_executor</span></code>
+          function. For example:
+        </p>
+<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">associated_executor_t</span><span class="special">&lt;</span><span class="identifier">Handler</span><span class="special">&gt;</span> <span class="identifier">a</span> <span class="special">=</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">get_associated_executor</span><span class="special">(</span><span class="identifier">h</span><span class="special">);</span>
+</pre>
+<p>
+          The associated executor must satisfy the Executor requirements. It will
+          be used by the asynchronous operation to submit both intermediate and final
+          handlers for execution.
+        </p>
+<p>
+          The executor may be customised for a particular handler type by specifying
+          a nested type <code class="computeroutput"><span class="identifier">executor_type</span></code>
+          and member function <code class="computeroutput"><span class="identifier">get_executor</span><span class="special">()</span></code>:

+          The implementation of this library for a particular platform may make use
+          of one or more internal threads to emulate asynchronicity. As far as possible,
+          these threads must be invisible to the library user. In particular, the
+          threads:
+        </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+              must not call the user's code directly; and
+            </li>
+<li class="listitem">
+              must block all signals.
+            </li>
+</ul></div>
+<p>
+          This approach is complemented by the following guarantee:
+        </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem">
+              Asynchronous completion handlers will only be called from threads that
+              are currently calling <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code>.
+            </li></ul></div>
+<p>
+          Consequently, it is the library user's responsibility to create and manage
+          all threads to which the notifications will be delivered.
+        </p>
+<p>
+          The reasons for this approach include:
+        </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+              By only calling <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code> from a single thread, the user's
+              code can avoid the development complexity associated with synchronisation.
+              For example, a library user can implement scalable servers that are
+              single-threaded (from the user's point of view).
+            </li>
+<li class="listitem">
+              A library user may need to perform initialisation in a thread shortly
+              after the thread starts and before any other application code is executed.
+              For example, users of Microsoft's COM must call <code class="computeroutput"><span class="identifier">CoInitializeEx</span></code>
+              before any other COM operations can be called from that thread.
+            </li>
+<li class="listitem">
+              The library interface is decoupled from interfaces for thread creation
+              and management, and permits implementations on platforms where threads
+              are not available.

+<p>
+          With C++11 and later, user-defined completion handlers are only required
+          to be move constructible, and are not required to be copy constructible.
+        </p>
+<p>
+          When move support is enabled, asynchronous that are documented as follows:
+        </p>
+<pre class="programlisting"><span class="keyword">template</span> <span class="special">&lt;</span><span class="keyword">typename</span> <span class="identifier">Handler</span><span class="special">&gt;</span>
+<span class="keyword">void</span> <span class="identifier">async_XYZ</span><span class="special">(...,</span> <span class="identifier">Handler</span> <span class="identifier">handler</span><span class="special">);</span>
+</pre>
+<p>
+          are actually declared as:
+        </p>
+<pre class="programlisting"><span class="keyword">template</span> <span class="special">&lt;</span><span class="keyword">typename</span> <span class="identifier">Handler</span><span class="special">&gt;</span>
+<span class="keyword">void</span> <span class="identifier">async_XYZ</span><span class="special">(...,</span> <span class="identifier">Handler</span><span class="special">&amp;&amp;</span> <span class="identifier">handler</span><span class="special">);</span>
+</pre>
+<p>
+          The handler argument is perfectly forwarded and the move construction occurs
+          within the body of <code class="computeroutput"><span class="identifier">async_XYZ</span><span class="special">()</span></code>. This ensures that all other function
+          arguments are evaluated prior to the move. This is critical when the other
+          arguments to <code class="computeroutput"><span class="identifier">async_XYZ</span><span class="special">()</span></code> are members of the handler. For example:
+        </p>

+          while there are pending asynchronous operations, but it is unlikely to

+          to the stream object. Moving during the composed operation means that the
+          composed operation may attempt to access a moved-from object.
+        </p>

+<p>
+        This section presents a high-level overview of the asynchronous model at
+        the core of the Asio library. This model enshrines asynchronous operations
+        as the fundamental building block of asynchronous composition, but in a way
+        that decouples them from the composition mechanism. The asynchronous operations
+        in Asio support callbacks, futures (both eager and lazy), fibers, coroutines,
+        and approaches yet to be imagined. This allows the application programmer
+        to select an approach based on appropriate trade-offs.

+<p>
+          Every asynchronous agent has an associated <span class="emphasis"><em>allocator</em></span>.
+          An agent's allocator is an interface used by the agent's asynchronous operations
+          to obtain <span class="emphasis"><em>per-operation stable memory</em></span> resources (POSMs).
+          This name reflects the fact that the memory is per-operation because the
+          memory is only retained for the lifetime of that operation, and stable,
+          because the memory is guaranteed to be available at that location throughout
+          the operation.
+        </p>
+<p>
+          Asynchronous operations may utilise POSMs in a number of different ways:
+        </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+              The operation doesn't require any POSMs. For example, the operation
+              wraps an existing API that performs its own memory management, or is
+              copying the long lived state into existing memory like a circular buffer.
+            </li>
+<li class="listitem">
+              The operation uses a single, fixed-size POSM for as long as the operation
+              is outstanding. For example, the operation stores some state in a linked
+              list.
+            </li>
+<li class="listitem">
+              The operation uses a single, runtime-sized POSM. For example, the operation
+              stores a copy of a user-supplied buffer, or a runtime-sized array of
+              iovec structures.
+            </li>
+<li class="listitem">
+              The operation uses multiple POSMs concurrently. For example, a fixed
+              size POSM for a linked list plus a runtime-sized POSM for a buffer.
+            </li>
+<li class="listitem">
+              The operation uses multiple POSMs serially, which may vary in size.
+            </li>
+</ul></div>
+<p>
+          Associated allocators allow users to treat POSM optimisation as a cross-cutting
+          concern to the composition of asynchronous operations. Furthermore, using
+          allocators as the interface to obtain POSMs grant substantial flexibility
+          to both the implementers and users of asynchronous operations:
+        </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+              Users can ignore the allocator and accept whatever default strategy
+              is employed by the application.
+            </li>
+<li class="listitem">
+              Implementers can ignore the allocator, especially if the operation
+              is not considered performance-sensitive.
+            </li>
+<li class="listitem">
+              Users can co-locate POSMs for related asynchronous operations, for
+              better locality of reference.
+            </li>
+<li class="listitem">
+              For compositions that involve serial POSMs of different sizes, memory
+              usage need only be as great as the currently extant POSM. For example,
+              consider a composition that contains a short-lived operation that uses
+              large POSMs (connection establishment and handshake) followed by a
+              long-lived operation that uses small POSMs (transferring data to and
+              from the peer).
+            </li>
+</ul></div>
+<p>
+          As noted previously, all resources must be released prior to calling the
+          completion handler. This enables memory to be recycled for subsequent asynchronous
+          operations within an agent. This allows applications with long-lived asynchronous
+          agents to have no hot-path memory allocations, even though the user code
+          is unaware of associated allocators.

+<p>
+          An <span class="emphasis"><em>asynchronous agent</em></span> is a sequential composition
+          of asynchronous operations. Every asynchronous operation is considered
+          to run as a part of an asynchronous agent, even if that agent contains
+          only that single operation. An asynchronous agent is an entity that may
+          perform work concurrently with other agents. Asynchronous agents are to
+          asynchronous operations as threads are to synchronous operations.
+        </p>
+<p>
+          However, an asynchronous agent is a purely notional construct that allows
+          us to reason about the context for, and composition of, asynchronous operations

+          An <span class="emphasis"><em>asynchronous operation</em></span> is the basic unit of composition
+          in the Asio asynchronous model. Asynchronous operations represent work
+          that is launched and performed in the background, while the user's code
+          that initiated the work can continue with other things.
+        </p>
+<p>
+          Conceptually, the lifecycle of an asynchronous operation can be described
+          in terms of the following events and phases:
+        </p>

+          An <span class="emphasis"><em>initiating function</em></span> is a function which may be
+          called by the user to start an asynchronous operation.
+        </p>
+<p>
+          A <span class="emphasis"><em>completion handler</em></span> is a user-provided, move-only
+          function object that will be invoked, at most once, with the result of
+          the asynchronous operation. The invocation of the completion handler tells
+          the user about something that has already happened: the operation completed,
+          and the side effects of the operation were established.
+        </p>
+<p>
+          The initiating function and completion handler are incorporated into the
+          user's code as follows:

+          Synchronous operations, being embodied as single functions, have several
+          inherent semantic properties as a consequence. Asynchronous operations
+          adopt some of these semantic properties from their synchronous counterparts,
+          in order to facilitate flexible and efficient composition.

+<p>
+          In Asio, many objects, such as sockets and timers, support object-wide
+          cancellation of outstanding asynchronous operations via their close or
+          cancel member functions. However, certain asynchronous operations also
+          support individual, targeted cancellation. This per-operation cancellation
+          is enabled by specifying that every asynchronous agent has an associated
+          <span class="emphasis"><em>cancellation slot</em></span>.
+        </p>
+<p>
+          To support cancellation, an asynchronous operation installs a cancellation
+          handler into the agent's slot. The cancellation handler is a function object
+          that will be invoked when a cancellation signal is emitted by the user
+          into the slot. Since a cancellation slot is associated with a single agent,
+          the slot holds at most one handler at a time, and installing a new handler
+          will overwrite any previously installed handler. Thus, the same slot is
+          reused for subsequent asynchronous operations within the agent.
+        </p>
+<p>
+          Cancellation is particularly useful when an asynchronous operation contains
+          multiple child agents. For example, one child agent may be complete and
+          the other is then cancelled, as its side effects are no longer required.

+<p>
+          A key goal of Asio's asynchronous model is to support multiple composition
+          mechanisms. This is achieved via a <span class="emphasis"><em>completion token</em></span>,
+          which the user passes to an asynchronous operation's initiating function
+          to customise the API surface of the library. By convention, the completion
+          token is the final argument to an asynchronous operation's initiating function.
+        </p>
+<p>
+          For example, if the user passes a lambda (or other function object) as
+          the completion token, the asynchronous operation behaves as previously
+          described: the operation begins, and when the operation completes the result
+          is passed to the lambda.

+          of a <code class="computeroutput"><span class="identifier">promise</span></code> and <code class="computeroutput"><span class="identifier">future</span></code> pair. The initiating function
+          does not just launch the operation, but also returns a future that may

+          completion token causes the initiating function to behave as a synchronous
+          operation within the context of a stackful coroutine. It not only begins
+          the asynchronous operation, but blocks the stackful coroutine until it
+          is complete. From the point of the stackful coroutine, it is a synchronous
+          operation.

+          All of these uses are supported by a single implementation of the <code class="computeroutput"><span class="identifier">async_read_some</span></code> initiating function.
+        </p>
+<p>
+          To achieve this, an asynchronous operation must first specify a <span class="emphasis"><em>completion
+          signature</em></span> (or, possibly, signatures) that describes the arguments
+          that will be passed to its completion handler.
+        </p>
+<p>
+          Then, the operation's initiating function takes the completion signature,
+          completion token, and its internal implementation and passes them to the
+          <span class="emphasis"><em>async_result</em></span> trait. The <code class="computeroutput"><span class="identifier">async_result</span></code>
+          trait is a customisation point that combines these to first produce a concrete
+          completion handler, and then launch the operation.

+<p>
+          The Asio library includes a low-level socket interface based on the BSD
+          socket API, which is widely implemented and supported by extensive literature.
+          It is also used as the basis for networking APIs in other languages, like
+          Java. This low-level interface is designed to support the development of
+          efficient and scalable applications. For example, it permits programmers
+          to exert finer control over the number of system calls, avoid redundant
+          data copying, minimise the use of resources like threads, and so on.
+        </p>
+<p>
+          Unsafe and error prone aspects of the BSD socket API are not included.
+          For example, the use of <code class="computeroutput"><span class="keyword">int</span></code>
+          to represent all sockets lacks type safety. The socket representation in
+          Asio uses a distinct type for each protocol, e.g. for TCP one would use
+          <code class="computeroutput"><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span></code>, and for UDP one uses <code class="computeroutput"><span class="identifier">ip</span><span class="special">::</span><span class="identifier">udp</span><span class="special">::</span><span class="identifier">socket</span></code>.
+        </p>
+<p>
+          The following table shows the mapping between the BSD socket API and Asio:

+<p>
+          Asio includes classes that implement iostreams on top of sockets. These
+          hide away the complexities associated with endpoint resolution, protocol
+          independence, etc. To create a connection one might simply write:
+        </p>
+<pre class="programlisting"><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">iostream</span> <span class="identifier">stream</span><span class="special">(</span><span class="string">"www.boost.org"</span><span class="special">,</span> <span class="string">"http"</span><span class="special">);</span>

+<span class="special">{</span>
+  <span class="comment">// Can't connect.</span>
+<span class="special">}</span>
+</pre>
+<p>
+          The iostream class can also be used in conjunction with an acceptor to
+          create simple servers. For example:
+        </p>
+<pre class="programlisting"><span class="identifier">io_context</span> <span class="identifier">ioc</span><span class="special">;</span>
+
+<span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">endpoint</span> <span class="identifier">endpoint</span><span class="special">(</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">v4</span><span class="special">(),</span> <span class="number">80</span><span class="special">);</span>

+  <span class="special">...</span>
+<span class="special">}</span>
+</pre>
+<p>
+          Timeouts may be set by calling <code class="computeroutput"><span class="identifier">expires_at</span><span class="special">()</span></code> or <code class="computeroutput"><span class="identifier">expires_from_now</span><span class="special">()</span></code> to establish a deadline. Any socket operations
+          that occur past the deadline will put the iostream into a "bad"
+          state.
+        </p>
+<p>
+          For example, a simple client program like this:
+        </p>
+<pre class="programlisting"><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">iostream</span> <span class="identifier">stream</span><span class="special">;</span>

+          If an error does occur, the iostream's <code class="computeroutput"><span class="identifier">error</span><span class="special">()</span></code> member function may be used to retrieve

+          When using C++11, it is possible to perform move construction from a socket

+</pre>
+<p>
+          For example, one possible conversion is from a TCP socket to a generic

+          to <code class="computeroutput"><span class="identifier">Protocol2</span></code> is valid,

+<p>
+          Asio provides basic support for UNIX domain sockets (also known as local
+          sockets). The simplest use involves creating a pair of connected sockets.
+          The following code:
+        </p>
+<pre class="programlisting"><span class="identifier">local</span><span class="special">::</span><span class="identifier">stream_protocol</span><span class="special">::</span><span class="identifier">socket</span> <span class="identifier">socket1</span><span class="special">(</span><span class="identifier">my_io_context</span><span class="special">);</span>

+</pre>
+<p>
+          will create a pair of stream-oriented sockets. To do the same for datagram-oriented
+          sockets, use:
+        </p>
+<pre class="programlisting"><span class="identifier">local</span><span class="special">::</span><span class="identifier">datagram_protocol</span><span class="special">::</span><span class="identifier">socket</span> <span class="identifier">socket1</span><span class="special">(</span><span class="identifier">my_io_context</span><span class="special">);</span>

+</pre>
+<p>
+          A UNIX domain socket server may be created by binding an acceptor to an
+          endpoint, in much the same way as one does for a TCP server:

+          A client that connects to this server might look like:

+          Transmission of file descriptors or credentials across UNIX domain sockets
+          is not directly supported within Asio, but may be achieved by accessing

+<p>
+          Asio includes classes added to permit synchronous and asynchronous read
+          and write operations to be performed on POSIX file descriptors, such as
+          pipes, standard input and output, and various devices.
+        </p>
+<p>
+          These classes also provide limited support for regular files. This support
+          assumes that the underlying read and write operations provided by the operating
+          system never fail with <code class="computeroutput"><span class="identifier">EAGAIN</span></code>
+          or <code class="computeroutput"><span class="identifier">EWOULDBLOCK</span></code>. (This assumption
+          normally holds for buffered file I/O.) Synchronous and asynchronous read
+          and write operations on file descriptors will succeed but the I/O will
+          always be performed immediately. Wait operations, and operations involving
+          <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">null_buffers</span></code>, are not portably supported.
+        </p>
+<p>
+          For example, to perform read and write operations on standard input and
+          output, the following objects may be created:
+        </p>
+<pre class="programlisting"><span class="identifier">posix</span><span class="special">::</span><span class="identifier">stream_descriptor</span> <span class="identifier">in</span><span class="special">(</span><span class="identifier">my_io_context</span><span class="special">,</span> <span class="special">::</span><span class="identifier">dup</span><span class="special">(</span><span class="identifier">STDIN_FILENO</span><span class="special">));</span>
+<span class="identifier">posix</span><span class="special">::</span><span class="identifier">stream_descriptor</span> <span class="identifier">out</span><span class="special">(</span><span class="identifier">my_io_context</span><span class="special">,</span> <span class="special">::</span><span class="identifier">dup</span><span class="special">(</span><span class="identifier">STDOUT_FILENO</span><span class="special">));</span>
+</pre>
+<p>
+          These are then used as synchronous or asynchronous read and write streams.
+          This means the objects can be used with any of the <a class="link" href="../../reference/read.html" title="read">read()</a>,
+          <a class="link" href="../../reference/async_read.html" title="async_read">async_read()</a>, <a class="link" href="../../reference/write.html" title="write">write()</a>,

+<p>
+        Most programs interact with the outside world in some way, whether it be
+        via a file, a network, a serial cable, or the console. Sometimes, as is the
+        case with networking, individual I/O operations can take a long time to complete.
+        This poses particular challenges to application development.
+      </p>
+<p>
+        Asio provides the tools to manage these long running operations, without
+        requiring programs to use concurrency models based on threads and explicit
+        locking.
+      </p>
+<p>
+        The Asio library is intended for programmers using C++ for systems programming,
+        where access to operating system functionality such as networking is often
+        required. In particular, Asio addresses the following goals:
+      </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+            <span class="bold"><strong>Portability.</strong></span> The library should support
+            a range of commonly used operating systems, and provide consistent behaviour
+            across these operating systems.
+          </li>
+<li class="listitem">
+            <span class="bold"><strong>Scalability.</strong></span> The library should facilitate

+<li class="listitem">
+            <span class="bold"><strong>Efficiency.</strong></span> The library should support

+            use a similar interface for networking APIs. As far as is reasonable,

+<li class="listitem">
+            <span class="bold"><strong>Ease of use.</strong></span> The library should provide
+            a lower entry barrier for new users by taking a toolkit, rather than

+            investment in time to just learning a few basic rules and guidelines.
+            After that, a library user should only need to understand the specific

+<li class="listitem">

+</ul></div>
+<p>
+        Although Asio started life focused primarily on networking, its concepts

+        Asio includes classes for creating and manipulating serial ports in a portable
+        manner. For example, a serial port may be opened using:
+      </p>
+<pre class="programlisting"><span class="identifier">serial_port</span> <span class="identifier">port</span><span class="special">(</span><span class="identifier">my_io_context</span><span class="special">,</span> <span class="identifier">name</span><span class="special">);</span>
+</pre>
+<p>
+        where name is something like <code class="computeroutput"><span class="string">"COM1"</span></code>
+        on Windows, and <code class="computeroutput"><span class="string">"/dev/ttyS0"</span></code>
+        on POSIX platforms.
+      </p>
+<p>
+        Once opened, the serial port may be used as a <a class="link" href="core/streams.html" title="Streams, Short Reads and Short Writes">stream</a>.
+        This means the objects can be used with any of the <a class="link" href="../reference/read.html" title="read">read()</a>,
+        <a class="link" href="../reference/async_read.html" title="async_read">async_read()</a>, <a class="link" href="../reference/write.html" title="write">write()</a>,

+        or <a class="link" href="../reference/async_read_until.html" title="async_read_until">async_read_until()</a>
+        free functions.
+      </p>
+<p>
+        The serial port implementation also includes option classes for configuring
+        the port's baud rate, flow control type, parity, stop bits and character
+        size.

+        Serial ports are available on all POSIX platforms. For Windows, serial ports
+        are only available at compile time when the I/O completion port backend is
+        used (which is the default). A program may test for the macro <code class="computeroutput"><span class="identifier">ASIO_HAS_SERIAL_PORT</span></code> to determine whether
+        they are supported.

+<p>
+        Asio contains classes and class templates for basic SSL support. These classes
+        allow encrypted communication to be layered on top of an existing stream,
+        such as a TCP socket.
+      </p>
+<p>
+        Before creating an encrypted stream, an application must construct an SSL
+        context object. This object is used to set SSL options such as verification
+        mode, certificate files, and so on. As an illustration, client-side initialisation
+        may look something like:
+      </p>
+<pre class="programlisting"><span class="identifier">ssl</span><span class="special">::</span><span class="identifier">context</span> <span class="identifier">ctx</span><span class="special">(</span><span class="identifier">ssl</span><span class="special">::</span><span class="identifier">context</span><span class="special">::</span><span class="identifier">sslv23</span><span class="special">);</span>

+<span class="identifier">ctx</span><span class="special">.</span><span class="identifier">load_verify_file</span><span class="special">(</span><span class="string">"ca.pem"</span><span class="special">);</span>
+</pre>
+<p>
+        To use SSL with a TCP socket, one may write:
+      </p>
+<pre class="programlisting"><span class="identifier">ssl</span><span class="special">::</span><span class="identifier">stream</span><span class="special">&lt;</span><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span><span class="special">&gt;</span> <span class="identifier">ssl_sock</span><span class="special">(</span><span class="identifier">my_io_context</span><span class="special">,</span> <span class="identifier">ctx</span><span class="special">);</span>
+</pre>
+<p>
+        To perform socket-specific operations, such as establishing an outbound connection
+        or accepting an incoming one, the underlying socket must first be obtained
+        using the <code class="computeroutput"><span class="identifier">ssl</span><span class="special">::</span><span class="identifier">stream</span></code> template's <a class="link" href="../reference/ssl__stream/lowest_layer.html" title="ssl::stream::lowest_layer"><code class="computeroutput"><span class="identifier">lowest_layer</span><span class="special">()</span></code></a>
+        member function:
+      </p>
+<pre class="programlisting"><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span><span class="special">::</span><span class="identifier">lowest_layer_type</span><span class="special">&amp;</span> <span class="identifier">sock</span> <span class="special">=</span> <span class="identifier">ssl_sock</span><span class="special">.</span><span class="identifier">lowest_layer</span><span class="special">();</span>
+<span class="identifier">sock</span><span class="special">.</span><span class="identifier">connect</span><span class="special">(</span><span class="identifier">my_endpoint</span><span class="special">);</span>
+</pre>
+<p>
+        In some use cases the underlying stream object will need to have a longer
+        lifetime than the SSL stream, in which case the template parameter should
+        be a reference to the stream type:
+      </p>
+<pre class="programlisting"><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span> <span class="identifier">sock</span><span class="special">(</span><span class="identifier">my_io_context</span><span class="special">);</span>

+</pre>
+<p>
+        SSL handshaking must be performed prior to transmitting or receiving data
+        over an encrypted connection. This is accomplished using the <code class="computeroutput"><span class="identifier">ssl</span><span class="special">::</span><span class="identifier">stream</span></code>
+        template's <a class="link" href="../reference/ssl__stream/handshake.html" title="ssl::stream::handshake">handshake()</a>
+        or <a class="link" href="../reference/ssl__stream/async_handshake.html" title="ssl::stream::async_handshake">async_handshake()</a>
+        member functions.
+      </p>
+<p>
+        Once connected, SSL stream objects are used as synchronous or asynchronous
+        read and write streams. This means the objects can be used with any of the
+        <a class="link" href="../reference/read.html" title="read">read()</a>, <a class="link" href="../reference/async_read.html" title="async_read">async_read()</a>,

+<p>
+        Long running I/O operations will often have a deadline by which they must
+        have completed. These deadlines may be expressed as absolute times, but are
+        often calculated relative to the current time.
+      </p>
+<p>
+        As a simple example, to perform a synchronous wait operation on a timer using
+        a relative time one may write:
+      </p>
+<pre class="programlisting"><span class="identifier">io_context</span> <span class="identifier">i</span><span class="special">;</span>
+<span class="special">...</span>

+<span class="identifier">t</span><span class="special">.</span><span class="identifier">wait</span><span class="special">();</span>
+</pre>
+<p>
+        More commonly, a program will perform an asynchronous wait operation on a
+        timer:
+      </p>
+<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">handler</span><span class="special">(</span><span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span> <span class="identifier">ec</span><span class="special">)</span> <span class="special">{</span> <span class="special">...</span> <span class="special">}</span>

+<span class="identifier">i</span><span class="special">.</span><span class="identifier">run</span><span class="special">();</span>
+</pre>
+<p>
+        The deadline associated with a timer may also be obtained as an absolute
+        time:
+      </p>
+<pre class="programlisting"><span class="identifier">steady_timer</span><span class="special">::</span><span class="identifier">time_point</span> <span class="identifier">time_of_expiry</span> <span class="special">=</span> <span class="identifier">t</span><span class="special">.</span><span class="identifier">expiry</span><span class="special">();</span>
+</pre>
+<p>
+        which allows composition of timers:
+      </p>
+<pre class="programlisting"><span class="identifier">steady_timer</span> <span class="identifier">t2</span><span class="special">(</span><span class="identifier">i</span><span class="special">);</span>

+          Asio contains classes to allow asynchronous read and write operations to

+          such as named pipes.
+        </p>
+<p>
+          For example, to perform asynchronous operations on a named pipe, the following
+          object may be created:
+        </p>
+<pre class="programlisting"><span class="identifier">HANDLE</span> <span class="identifier">handle</span> <span class="special">=</span> <span class="special">::</span><span class="identifier">CreateFile</span><span class="special">(...);</span>

+</pre>
+<p>
+          These are then used as synchronous or asynchronous read and write streams.
+          This means the objects can be used with any of the <a class="link" href="../../reference/read.html" title="read">read()</a>,
+          <a class="link" href="../../reference/async_read.html" title="async_read">async_read()</a>, <a class="link" href="../../reference/write.html" title="write">write()</a>,
+          <a class="link" href="../../reference/async_write.html" title="async_write">async_write()</a>, <a class="link" href="../../reference/read_until.html" title="read_until">read_until()</a> or <a class="link" href="../../reference/async_read_until.html" title="async_read_until">async_read_until()</a>
+          free functions.
+        </p>
+<p>
+          The kernel object referred to by the <code class="computeroutput"><span class="identifier">HANDLE</span></code>
+          must support use with I/O completion ports (which means that named pipes
+          are supported, but anonymous pipes and console streams are not).

+        A dynamic buffer encapsulates memory storage that may be automatically resized
+        as required, where the memory is divided into an input sequence followed
+        by an output sequence. These memory regions are internal to the dynamic buffer
+        sequence, but direct access to the elements is provided to permit them to
+        be efficiently used with I/O operations, such as the <code class="computeroutput"><span class="identifier">send</span></code>
+        or <code class="computeroutput"><span class="identifier">receive</span></code> operations of
+        a socket. Data written to the output sequence of a dynamic buffer sequence
+        object is appended to the input sequence of the same object.
+      </p>
+<p>
+        A dynamic buffer type <code class="computeroutput"><span class="identifier">X</span></code> shall
+        satisfy the requirements of <code class="computeroutput"><span class="identifier">MoveConstructible</span></code>
+        (C++ Std, [moveconstructible]) types in addition to those listed below.
+      </p>

+        A receiver represents the continuation of an asynchronous operation. An asynchronous
+        operation may complete with a (possibly empty) set of values, an error, or
+        it may be cancelled. A receiver has three principal operations corresponding
+        to the three ways an asynchronous operation may complete: <code class="computeroutput"><span class="identifier">set_value</span></code>,
+        <code class="computeroutput"><span class="identifier">set_error</span></code>, and <code class="computeroutput"><span class="identifier">set_done</span></code>. These are collectively known
+        as a receiver’s <span class="emphasis"><em>completion-signal operations</em></span>.

+        The <code class="computeroutput"><span class="identifier">basic_waitable_timer</span></code>

+        [<span class="emphasis"><em>Note:</em></span> Possible uses of wait traits include:<br> — To

+        errors or rounding timeouts to boundaries.<br> — Preventing duration overflow.

+        Asynchronous operations may need to allocate temporary objects. Since asynchronous

+        said to be associated with the handler.
+      </p>
+<p>
+        Implement asio_handler_allocate and asio_handler_deallocate for your own
+        handlers to provide custom allocation for these temporary objects.
+      </p>
+<p>
+        The default implementation of these allocation hooks uses <code class="computeroutput"><span class="keyword">operator</span>
+        <span class="keyword">new</span></code> and <code class="computeroutput"><span class="keyword">operator</span>

+        All temporary objects associated with a handler will be deallocated before

+        Completion handlers for asynchronous operations are invoked by the <a class="link" href="io_context.html" title="io_context"><code class="computeroutput"><span class="identifier">io_context</span></code></a>
+        associated with the corresponding object (e.g. a socket or deadline_timer).
+        Certain guarantees are made on when the handler may be invoked, in particular
+        that a handler can only be invoked from a thread that is currently calling
+        <code class="computeroutput"><span class="identifier">run</span><span class="special">()</span></code>
+        on the corresponding <a class="link" href="io_context.html" title="io_context"><code class="computeroutput"><span class="identifier">io_context</span></code></a> object. Handlers may
+        subsequently be invoked through other objects (such as <a class="link" href="io_context__strand.html" title="io_context::strand"><code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">strand</span></code></a> objects) that provide additional
+        guarantees.
+      </p>
+<p>
+        When asynchronous operations are composed from other asynchronous operations,
+        all intermediate handlers should be invoked using the same method as the
+        final handler. This is required to ensure that user-defined objects are not
+        accessed in a way that may violate the guarantees. This hooking function
+        ensures that the invoked method used for the final handler is accessible
+        at each intermediate step.
+      </p>
+<p>
+        Implement asio_handler_invoke for your own handlers to specify a custom invocation
+        strategy.
+      </p>
+<p>
+        This default implementation invokes the function object like so:
+      </p>
+<pre class="programlisting"><span class="identifier">function</span><span class="special">();</span>
+</pre>
+<p>
+        If necessary, the default implementation makes a copy of the function object
+        so that the non-const operator() can be used.
+      </p>

+          operation</a>, and always returns immediately. The asynchronous operation
+          will continue until one of the following conditions is true:

+          This function is used to asynchronously read data into the specified dynamic
+          buffer sequence until a user-defined match condition function object, when
+          applied to the data contained in the dynamic buffer sequence, indicates
+          a successful match. It is an initiating function for an <a class="link" href="../../overview/model/async_ops.html" title="Asynchronous Operations">asynchronous
+          operation</a>, and always returns immediately. The asynchronous operation
+          will continue until one of the following conditions is true:

+          If the match condition function object already indicates a match, this

+          data that matches a regular expression. It is an initiating function for
+          an <a class="link" href="../../overview/model/async_ops.html" title="Asynchronous Operations">asynchronous operation</a>,
+          and always returns immediately. The asynchronous operation will continue

+          (such as async_read, async_read_until, the stream's async_read_some function,

+          applied to the data contained in the dynamic buffer sequence, indicates
+          a successful match. It is an initiating function for an <a class="link" href="../../overview/model/async_ops.html" title="Asynchronous Operations">asynchronous
+          operation</a>, and always returns immediately. The asynchronous operation
+          will continue until one of the following conditions is true:

+          data contained in the streambuf, indicates a successful match. It is an
+          initiating function for an <a class="link" href="../../overview/model/async_ops.html" title="Asynchronous Operations">asynchronous
+          operation</a>, and always returns immediately. The asynchronous operation

+          operation</a>, and always returns immediately. The asynchronous operation

+<p>
+        An <span class="emphasis"><em>initiating function</em></span> is a function which may be called
+        to start an asynchronous operation. A <span class="emphasis"><em>completion handler</em></span>
+        is a function object that will be invoked, at most once, with the result
+        of the asynchronous operation.
+      </p>
+<p>
+        The lifecycle of an asynchronous operation is comprised of the following
+        events and phases:
+      </p>
+<p>
+        — Event 1: The asynchronous operation is started by a call to the initiating
+        function.
+      </p>
+<p>
+        — Phase 1: The asynchronous operation is now <span class="emphasis"><em>outstanding</em></span>.
+      </p>
+<p>
+        — Event 2: The externally observable side effects of the asynchronous operation,
+        if any, are fully established. The completion handler is submitted to an
+        executor.
+      </p>
+<p>
+        — Phase 2: The asynchronous operation is now <span class="emphasis"><em>completed</em></span>.
+      </p>
+<p>
+        — Event 3: The completion handler is called with the result of the asynchronous
+        operation.
+      </p>
+<p>
+        In this library, all functions with the prefix <code class="computeroutput"><span class="identifier">async_</span></code>
+        are initiating functions.

+      </p>

+        <code class="computeroutput"><span class="identifier">token</span></code> of type <code class="computeroutput"><span class="identifier">CompletionToken</span></code>;
+      </p>

+        — specify one or more <span class="emphasis"><em>completion signatures</em></span>, referred
+        to below as a variadic pack of call signatures (C++Std [func.def]) <code class="computeroutput"><span class="identifier">Signatures</span></code>, that determine the possible
+        argument sets to the completion handler.
+      </p>
+<p>
+        In this library, initiating functions specify a <span class="emphasis"><em>Completion signature</em></span>
+        element that defines the call signatures <code class="computeroutput"><span class="identifier">Signatures</span></code>.
+        The <span class="emphasis"><em>Completion signature</em></span> elements in this library may
+        have named parameters, and the results of an asynchronous operation may be
+        specified in terms of these names.
+      </p>
+<p>
+        Completion token behaviour is determined through specialisation of the <code class="computeroutput"><span class="identifier">async_result</span></code> trait. These specialisations

+            when run on Windows XP, Windows Server 2003, and earlier versions of
+            Windows, unless ASIO_ENABLE_CANCELIO is defined. However, the CancelIo
+            function has two issues that should be considered before enabling its
+            use:
+          </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+                It will only cancel asynchronous operations that were initiated in
+                the current thread.
+              </li>
+<li class="listitem">
+                It can appear to complete without error, but the request to cancel
+                the unfinished operations may be silently ignored by the operating
+                system. Whether it works or not seems to depend on the drivers that
+                are installed.
+              </li>
+</ul></div>
+<p>
+            For portable cancellation, consider using one of the following alternatives:
+          </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+                Disable asio's I/O completion port backend by defining ASIO_DISABLE_IOCP.
+              </li>
+<li class="listitem">
+                Use the <code class="computeroutput"><span class="identifier">close</span><span class="special">()</span></code>
+                function to simultaneously cancel the outstanding operations and
+                close the socket.
+              </li>
+</ul></div>
+<p>
+            When running on Windows Vista, Windows Server 2008, and later, the CancelIoEx
+            function is always used. This function does not have the problems described
+            above.

+<p>
+        If a signal is registered with a signal_set, and the signal occurs when there
+        are no waiting handlers, then the signal notification is queued. The next
+        async_wait operation on that signal_set will dequeue the notification. If
+        multiple notifications are queued, subsequent async_wait operations dequeue
+        them one at a time. Signal notifications are dequeued in order of ascending
+        signal number.
+      </p>
+<p>
+        If a signal number is removed from a signal_set (using the <code class="computeroutput"><span class="identifier">remove</span></code> or <code class="computeroutput"><span class="identifier">erase</span></code>
+        member functions) then any queued notifications for that signal are discarded.

+        The same signal number may be registered with different signal_set objects.
+        When the signal occurs, one handler is called for each signal_set object.
+      </p>
+<p>
+        Note that multiple registration only works for signals that are registered
+        using Asio. The application must not also register a signal handler using

+<p>
+          If a signal is registered with a signal_set, and the signal occurs when
+          there are no waiting handlers, then the signal notification is queued.
+          The next async_wait operation on that signal_set will dequeue the notification.
+          If multiple notifications are queued, subsequent async_wait operations
+          dequeue them one at a time. Signal notifications are dequeued in order
+          of ascending signal number.
+        </p>
+<p>
+          If a signal number is removed from a signal_set (using the <code class="computeroutput"><span class="identifier">remove</span></code> or <code class="computeroutput"><span class="identifier">erase</span></code>
+          member functions) then any queued notifications for that signal are discarded.

+          The <code class="computeroutput"><span class="identifier">basic_streambuf</span></code> class
+          is derived from <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">streambuf</span></code> to associate the streambuf's
+          input and output sequences with one or more character arrays. These character
+          arrays are internal to the <code class="computeroutput"><span class="identifier">basic_streambuf</span></code>
+          object, but direct access to the array elements is provided to permit them
+          to be used efficiently with I/O operations. Characters written to the output
+          sequence of a <code class="computeroutput"><span class="identifier">basic_streambuf</span></code>
+          object are appended to the input sequence of the same object.

+          The <code class="computeroutput"><span class="identifier">basic_streambuf</span></code> class's

+<li class="listitem">
+              A sequence of one or more character arrays, where each array is of
+              the same size. Additional character array objects are appended to the

+<p>

+          The <code class="computeroutput"><span class="identifier">basic_streambuf</span></code> class
+          is derived from <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">streambuf</span></code> to associate the streambuf's
+          input and output sequences with one or more character arrays. These character
+          arrays are internal to the <code class="computeroutput"><span class="identifier">basic_streambuf</span></code>
+          object, but direct access to the array elements is provided to permit them
+          to be used efficiently with I/O operations. Characters written to the output
+          sequence of a <code class="computeroutput"><span class="identifier">basic_streambuf</span></code>

+        The system executor represents an execution context where functions are permitted

+        the system executor will schedule the function to run on an unspecified system
+        thread pool. When either blocking.possibly or blocking.always is established,
+        the executor invokes the function immediately.

+        A buffer object represents a contiguous region of memory as a 2-tuple consisting
+        of a pointer and size in bytes. A tuple of the form <code class="computeroutput"><span class="special">{</span><span class="keyword">void</span><span class="special">*,</span> <span class="identifier">size_t</span><span class="special">}</span></code> specifies a mutable (modifiable) region
+        of memory. Similarly, a tuple of the form <code class="computeroutput"><span class="special">{</span><span class="keyword">const</span> <span class="keyword">void</span><span class="special">*,</span> <span class="identifier">size_t</span><span class="special">}</span></code> specifies a const (non-modifiable) region
+        of memory. These two forms correspond to the classes <a class="link" href="mutable_buffer.html" title="mutable_buffer"><code class="computeroutput"><span class="identifier">mutable_buffer</span></code></a> and <a class="link" href="const_buffer.html" title="const_buffer"><code class="computeroutput"><span class="identifier">const_buffer</span></code></a>, respectively. To mirror
+        C++'s conversion rules, a <a class="link" href="mutable_buffer.html" title="mutable_buffer"><code class="computeroutput"><span class="identifier">mutable_buffer</span></code></a> is implicitly convertible
+        to a <a class="link" href="const_buffer.html" title="const_buffer"><code class="computeroutput"><span class="identifier">const_buffer</span></code></a>,
+        and the opposite conversion is not permitted.
+      </p>
+<p>
+        The simplest use case involves reading or writing a single buffer of a specified
+        size:
+      </p>
+<pre class="programlisting"><span class="identifier">sock</span><span class="special">.</span><span class="identifier">send</span><span class="special">(</span><span class="identifier">asio</span><span class="special">::</span><span class="identifier">buffer</span><span class="special">(</span><span class="identifier">data</span><span class="special">,</span> <span class="identifier">size</span><span class="special">));</span>
+</pre>
+<p>
+        In the above example, the return value of <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">buffer</span></code>
+        meets the requirements of the ConstBufferSequence concept so that it may
+        be directly passed to the socket's write function. A buffer created for modifiable
+        memory also meets the requirements of the MutableBufferSequence concept.
+      </p>
+<p>
+        An individual buffer may be created from a builtin array, std::vector, std::array
+        or boost::array of POD elements. This helps prevent buffer overruns by automatically
+        determining the size of the buffer:

+        The <code class="computeroutput"><span class="identifier">coroutine</span></code> class may be
+        used to implement stackless coroutines. The class itself is used to store
+        the current state of the coroutine.
+      </p>
+<p>
+        Coroutines are copy-constructible and assignable, and the space overhead
+        is a single int. They can be used as a base class:
+      </p>
+<pre class="programlisting"><span class="keyword">class</span> <span class="identifier">session</span> <span class="special">:</span> <span class="identifier">coroutine</span>
+<span class="special">{</span>
+  <span class="special">...</span>
+<span class="special">};</span>
+</pre>
+<p>
+        or as a data member:
+      </p>
+<pre class="programlisting"><span class="keyword">class</span> <span class="identifier">session</span>
+<span class="special">{</span>
+  <span class="special">...</span>
+  <span class="identifier">coroutine</span> <span class="identifier">coro_</span><span class="special">;</span>
+<span class="special">};</span>
+</pre>
+<p>
+        or even bound in as a function argument using lambdas or <code class="computeroutput"><span class="identifier">bind</span><span class="special">()</span></code>. The important thing is that as the application
+        maintains a copy of the object for as long as the coroutine must be kept
+        alive.
+      </p>
+<h5>
+<a name="asio.reference.coroutine.h1"></a>

+      </h5>
+<p>
+        A coroutine is used in conjunction with certain "pseudo-keywords",
+        which are implemented as macros. These macros are defined by a header file:
+      </p>
+<pre class="programlisting"><span class="preprocessor">#include</span> <span class="special">&lt;</span><span class="identifier">asio</span><span class="special">/</span><span class="identifier">yield</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span>
+</pre>
+<p>
+        and may conversely be undefined as follows:
+      </p>
+<pre class="programlisting"><span class="preprocessor">#include</span> <span class="special">&lt;</span><span class="identifier">asio</span><span class="special">/</span><span class="identifier">unyield</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span>
+</pre>
+<p>
+        <span class="bold"><strong>reenter</strong></span>
+      </p>
+<p>
+        The <code class="computeroutput"><span class="identifier">reenter</span></code> macro is used
+        to define the body of a coroutine. It takes a single argument: a pointer
+        or reference to a coroutine object. For example, if the base class is a coroutine
+        object you may write:
+      </p>
+<pre class="programlisting"><span class="identifier">reenter</span> <span class="special">(</span><span class="keyword">this</span><span class="special">)</span>
+<span class="special">{</span>
+  <span class="special">...</span> <span class="identifier">coroutine</span> <span class="identifier">body</span> <span class="special">...</span>
+<span class="special">}</span>
+</pre>
+<p>
+        and if a data member or other variable you can write:
+      </p>
+<pre class="programlisting"><span class="identifier">reenter</span> <span class="special">(</span><span class="identifier">coro_</span><span class="special">)</span>
+<span class="special">{</span>
+  <span class="special">...</span> <span class="identifier">coroutine</span> <span class="identifier">body</span> <span class="special">...</span>
+<span class="special">}</span>
+</pre>
+<p>
+        When <code class="computeroutput"><span class="identifier">reenter</span></code> is executed
+        at runtime, control jumps to the location of the last <code class="computeroutput"><span class="identifier">yield</span></code>
+        or <code class="computeroutput"><span class="identifier">fork</span></code>.
+      </p>
+<p>
+        The coroutine body may also be a single statement, such as:
+      </p>
+<pre class="programlisting"><span class="identifier">reenter</span> <span class="special">(</span><span class="keyword">this</span><span class="special">)</span> <span class="keyword">for</span> <span class="special">(;;)</span>
+<span class="special">{</span>
+  <span class="special">...</span>
+<span class="special">}</span>
+</pre>
+<p>
+        <span class="bold"><strong>Limitation:</strong></span> The <code class="computeroutput"><span class="identifier">reenter</span></code>
+        macro is implemented using a switch. This means that you must take care when
+        using local variables within the coroutine body. The local variable is not
+        allowed in a position where reentering the coroutine could bypass the variable
+        definition.
+      </p>
+<p>
+        <span class="bold"><strong>yield <span class="emphasis"><em>statement</em></span></strong></span>
+      </p>
+<p>
+        This form of the <code class="computeroutput"><span class="identifier">yield</span></code> keyword
+        is often used with asynchronous operations:
+      </p>
+<pre class="programlisting"><span class="identifier">yield</span> <span class="identifier">socket_</span><span class="special">-&gt;</span><span class="identifier">async_read_some</span><span class="special">(</span><span class="identifier">buffer</span><span class="special">(*</span><span class="identifier">buffer_</span><span class="special">),</span> <span class="special">*</span><span class="keyword">this</span><span class="special">);</span>
+</pre>
+<p>
+        This divides into four logical steps:
+      </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+            <code class="computeroutput"><span class="identifier">yield</span></code> saves the current
+            state of the coroutine.
+          </li>
+<li class="listitem">
+            The statement initiates the asynchronous operation.
+          </li>
+<li class="listitem">
+            The resume point is defined immediately following the statement.
+          </li>
+<li class="listitem">
+            Control is transferred to the end of the coroutine body.
+          </li>
+</ul></div>
+<p>
+        When the asynchronous operation completes, the function object is invoked
+        and <code class="computeroutput"><span class="identifier">reenter</span></code> causes control
+        to transfer to the resume point. It is important to remember to carry the
+        coroutine state forward with the asynchronous operation. In the above snippet,
+        the current class is a function object object with a coroutine object as
+        base class or data member.
+      </p>
+<p>
+        The statement may also be a compound statement, and this permits us to define
+        local variables with limited scope:
+      </p>

+</ul></div>
+<p>
+        Once terminated, calls to <code class="computeroutput"><span class="identifier">is_complete</span><span class="special">()</span></code> return true and the coroutine cannot be
+        reentered.
+      </p>
+<p>
+        Note that a coroutine may also be implicitly terminated if the coroutine
+        body is exited without a yield, e.g. by return, throw or by running to the
+        end of the body.

+<p>
+        The logical steps involved in a <code class="computeroutput"><span class="identifier">fork</span></code>

+<div class="itemizedlist"><ul class="itemizedlist" type="disc">

+<li class="listitem">

+</ul></div>
+<p>
+        The functions <code class="computeroutput"><span class="identifier">is_parent</span><span class="special">()</span></code>
+        and <code class="computeroutput"><span class="identifier">is_child</span><span class="special">()</span></code>
+        can be used to differentiate between parent and child. You would use these

+      </p>
+<p>
+        Note that <code class="computeroutput"><span class="identifier">fork</span></code> doesn't do
+        the actual forking by itself. It is the application's responsibility to create
+        a clone of the coroutine and call it. The clone can be called immediately,
+        as above, or scheduled for delayed execution using something like <a class="link" href="post.html" title="post"><code class="computeroutput"><span class="identifier">post</span></code></a>.

+        The <a class="link" href="deferred_t.html" title="deferred_t"><code class="computeroutput"><span class="identifier">deferred_t</span></code></a>
+        class is used to indicate that an asynchronous operation should return a
+        function object which is itself an initiation function. A <a class="link" href="deferred_t.html" title="deferred_t"><code class="computeroutput"><span class="identifier">deferred_t</span></code></a> object may be passed
+        as a completion token to an asynchronous operation, typically using the special
+        value <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">deferred</span></code>. For example:
+      </p>
+<pre class="programlisting"><span class="keyword">auto</span> <span class="identifier">my_deferred_op</span>
+  <span class="special">=</span> <span class="identifier">my_socket</span><span class="special">.</span><span class="identifier">async_read_some</span><span class="special">(</span><span class="identifier">my_buffer</span><span class="special">,</span>
+      <span class="identifier">asio</span><span class="special">::</span><span class="identifier">deferred</span><span class="special">);</span>
+</pre>
+<p>
+        The initiating function (async_read_some in the above example) returns a
+        function object that will lazily initiate the operation.

+        Services exist to manage the resources that are shared across an execution

+<p>
+        Access to the services of an <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput"><span class="identifier">execution_context</span></code></a> is via three function

+        its value <code class="computeroutput"><span class="identifier">use_coro</span></code>, is used
+        to represent an operation that can be awaited by the current resumable coroutine.
+        This completion token may be passed as a handler to an asynchronous operation.
+        For example:
+      </p>
+<pre class="programlisting"><span class="identifier">coro</span><span class="special">&lt;</span><span class="keyword">void</span><span class="special">&gt;</span> <span class="identifier">my_coroutine</span><span class="special">(</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span> <span class="identifier">my_socket</span><span class="special">)</span>

+  <span class="special">...</span>
+<span class="special">}</span>
+</pre>
+<p>
+        When used with co_await, the initiating function (<code class="computeroutput"><span class="identifier">async_read_some</span></code>
+        in the above example) suspends the current coroutine. The coroutine is resumed
+        when the asynchronous operation completes, and the result of the operation
+        is returned.
+      </p>
+<p>
+        Note that this token is not the most efficient (use <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">deferred</span></code>
+        for that) but does provide type erasure, as it will always return a <code class="computeroutput"><span class="identifier">coro</span></code>.

+        Note that multiple registration only works for signals that are registered

+        operation should return a std::future object. A <a class="link" href="use_future_t.html" title="use_future_t"><code class="computeroutput"><span class="identifier">use_future_t</span></code></a> object may be passed
+        as a completion token to an asynchronous operation, typically using the special
+        value <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">use_future</span></code>. For example:
+      </p>
+<pre class="programlisting"><span class="identifier">std</span><span class="special">::</span><span class="identifier">future</span><span class="special">&lt;</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">size_t</span><span class="special">&gt;</span> <span class="identifier">my_future</span>
+  <span class="special">=</span> <span class="identifier">my_socket</span><span class="special">.</span><span class="identifier">async_read_some</span><span class="special">(</span><span class="identifier">my_buffer</span><span class="special">,</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">use_future</span><span class="special">);</span>
+</pre>
+<p>
+        The initiating function (async_read_some in the above example) returns a
+        future that will receive the result of the operation. If the operation completes
+        with an <a class="link" href="error_code.html" title="error_code"><code class="computeroutput"><span class="identifier">error_code</span></code></a>
+        indicating failure, it is converted into a <a class="link" href="system_error.html" title="system_error"><code class="computeroutput"><span class="identifier">system_error</span></code></a> and passed back to
+        the caller via the future.

+      Asio provides a complete implementation of the proposed standard executors,
+      as described in <a href="http://wg21.link/P0443r13" target="_top">P0443r13</a>, <a href="http://wg21.link/P1348r0" target="_top">P1348r0</a>, and <a href="http://wg21.link/P1393r0" target="_top">P1393r0</a>.
+    </p>
+<p>
+      Just as with executors under the Networking TS model, a standard executor represents
+      a policy as to how, when, and where a piece of code should be executed. Most
+      existing code should continue to work with little or no change.

+        This tutorial program shows how to use asio to implement a client application
+        with TCP.
+      </p>
+<p>
+        We start by including the necessary header files.

+        The purpose of this application is to access a daytime service, so we need
+        the user to specify the server.

+    <span class="special">}</span>
+</pre>
+<p>
+        All programs that use asio need to have at least one I/O execution context,
+        such as an <a class="link" href="../reference/io_context.html" title="io_context">io_context</a> object.
+      </p>
+<pre class="programlisting">    <span class="identifier">asio</span><span class="special">::</span><span class="identifier">io_context</span> <span class="identifier">io_context</span><span class="special">;</span>
+</pre>
+<p>
+        We need to turn the server name that was specified as a parameter to the
+        application, into a TCP endpoint. To do this we use an <a class="link" href="../reference/ip__tcp/resolver.html" title="ip::tcp::resolver">ip::tcp::resolver</a>
+        object.
+      </p>
+<pre class="programlisting">    <span class="identifier">tcp</span><span class="special">::</span><span class="identifier">resolver</span> <span class="identifier">resolver</span><span class="special">(</span><span class="identifier">io_context</span><span class="special">);</span>
+</pre>
+<p>
+        A resolver takes a host name and service name and turns them into a list
+        of endpoints. We perform a resolve call using the name of the server, specified
+        in <code class="computeroutput"><span class="identifier">argv</span><span class="special">[</span><span class="number">1</span><span class="special">]</span></code>, and the
+        name of the service, in this case <code class="computeroutput"><span class="string">"daytime"</span></code>.
+      </p>
+<p>
+        The list of endpoints is returned using an object of type <a class="link" href="../reference/ip__basic_resolver/results_type.html" title="ip::basic_resolver::results_type">ip::tcp::resolver::results_type</a>.
+        This object is a range, with begin() and end() member functions that may
+        be used for iterating over the results.
+      </p>
+<pre class="programlisting">    <span class="identifier">tcp</span><span class="special">::</span><span class="identifier">resolver</span><span class="special">::</span><span class="identifier">results_type</span> <span class="identifier">endpoints</span> <span class="special">=</span>
+      <span class="identifier">resolver</span><span class="special">.</span><span class="identifier">resolve</span><span class="special">(</span><span class="identifier">argv</span><span class="special">[</span><span class="number">1</span><span class="special">],</span> <span class="string">"daytime"</span><span class="special">);</span>
+</pre>
+<p>
+        Now we create and connect the socket. The list of endpoints obtained above
+        may contain both IPv4 and IPv6 endpoints, so we need to try each of them
+        until we find one that works. This keeps the client program independent of
+        a specific IP version. The asio::connect() function does this for us automatically.
+      </p>
+<pre class="programlisting">    <span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span> <span class="identifier">socket</span><span class="special">(</span><span class="identifier">io_context</span><span class="special">);</span>

+</pre>
+<p>
+        The connection is open. All we need to do now is read the response from the
+        daytime service.
+      </p>
+<p>
+        We use a <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">array</span></code> to hold the received data. The asio::buffer()
+        function automatically determines the size of the array to help prevent buffer
+        overruns. Instead of a <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">array</span></code>,
+        we could have used a <code class="computeroutput"><span class="keyword">char</span> <span class="special">[]</span></code>
+        or <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span></code>.

+<p>

+        function will exit with the asio::error::eof error, which is how we know

+        Since UDP is datagram-oriented, we will not be using a stream socket. Create

+<p>
+        This tutorial program introduces asio by showing how to perform a blocking
+        wait on a timer.
+      </p>
+<p>
+        We start by including the necessary header files.
+      </p>
+<p>
+        All of the asio classes can be used by simply including the <code class="computeroutput"><span class="string">"asio.hpp"</span></code> header file.
+      </p>
+<pre class="programlisting"><span class="special">#</span><span class="identifier">include</span> <span class="special">&lt;</span><span class="identifier">iostream</span><span class="special">&gt;</span>
+<span class="special">#</span><span class="identifier">include</span> <span class="special">&lt;</span><span class="identifier">asio</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span>
+</pre>
+<p>
+        All programs that use asio need to have at least one I/O execution context,
+        such as an <a class="link" href="../reference/io_context.html" title="io_context">io_context</a> or
+        <a class="link" href="../reference/thread_pool.html" title="thread_pool">thread_pool</a> object. An
+        I/O execution context provides access to I/O functionality. We declare an
+        object of type <a class="link" href="../reference/io_context.html" title="io_context">io_context</a>
+        first thing in the main function.
+      </p>
+<pre class="programlisting"><span class="keyword">int</span> <span class="identifier">main</span><span class="special">()</span>
+<span class="special">{</span>
+  <span class="identifier">asio</span><span class="special">::</span><span class="identifier">io_context</span> <span class="identifier">io</span><span class="special">;</span>
+</pre>
+<p>
+        Next we declare an object of type asio::steady_timer. The core asio classes
+        that provide I/O functionality (or as in this case timer functionality) always
+        take an executor, or a reference to an execution context (such as <a class="link" href="../reference/io_context.html" title="io_context">io_context</a>),
+        as their first constructor argument. The second argument to the constructor
+        sets the timer to expire 5 seconds from now.
+      </p>
+<pre class="programlisting">  <span class="identifier">asio</span><span class="special">::</span><span class="identifier">steady_timer</span> <span class="identifier">t</span><span class="special">(</span><span class="identifier">io</span><span class="special">,</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">chrono</span><span class="special">::</span><span class="identifier">seconds</span><span class="special">(</span><span class="number">5</span><span class="special">));</span>
+</pre>
+<p>
+        In this simple example we perform a blocking wait on the timer. That is,
+        the call to <a class="link" href="../reference/basic_waitable_timer/wait.html" title="basic_waitable_timer::wait">steady_timer::wait()</a>
+        will not return until the timer has expired, 5 seconds after it was created
+        (i.e. not from when the wait starts).
+      </p>
+<p>
+        A timer is always in one of two states: "expired" or "not
+        expired". If the <a class="link" href="../reference/basic_waitable_timer/wait.html" title="basic_waitable_timer::wait">steady_timer::wait()</a>
+        function is called on an expired timer, it will return immediately.
+      </p>
+<pre class="programlisting">  <span class="identifier">t</span><span class="special">.</span><span class="identifier">wait</span><span class="special">();</span>
+</pre>
+<p>
+        Finally we print the obligatory <code class="computeroutput"><span class="string">"Hello,
+        world!"</span></code> message to show when the timer has expired.
+      </p>
+<pre class="programlisting">  <span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span> <span class="special">&lt;&lt;</span> <span class="string">"Hello, world!"</span> <span class="special">&lt;&lt;</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">endl</span><span class="special">;</span>

+<p>
+        This tutorial program demonstrates how to use asio's asynchronous functionality
+        by modifying the program from tutorial Timer.1 to perform an asynchronous
+        wait on the timer.
+      </p>
+<pre class="programlisting"><span class="special">#</span><span class="identifier">include</span> <span class="special">&lt;</span><span class="identifier">iostream</span><span class="special">&gt;</span>

+</pre>
+<p>
+        Using asio's asynchronous functionality means supplying a <a class="link" href="../overview/model/completion_tokens.html" title="Completion Tokens">completion
+        token</a>, which determines how the result will be delivered to a <span class="bold"><strong>completion handler</strong></span> when an <a class="link" href="../overview/model/async_ops.html" title="Asynchronous Operations">asynchronous
+        operation</a> completes. In this program we define a function called
+        <code class="computeroutput"><span class="identifier">print</span></code> to be called when the
+        asynchronous wait finishes.
+      </p>
+<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">print</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span><span class="special">&amp;</span> <span class="comment">/*e*/</span><span class="special">)</span>

+</pre>
+<p>
+        Next, instead of doing a blocking wait as in tutorial Timer.1, we call the
+        <a class="link" href="../reference/basic_waitable_timer/async_wait.html" title="basic_waitable_timer::async_wait">steady_timer::async_wait()</a>
+        function to perform an asynchronous wait. When calling this function we pass
+        the <code class="computeroutput"><span class="identifier">print</span></code> function that was
+        defined above.
+      </p>
+<pre class="programlisting">  <span class="identifier">t</span><span class="special">.</span><span class="identifier">async_wait</span><span class="special">(&amp;</span><span class="identifier">print</span><span class="special">);</span>
+</pre>
+<p>
+        Finally, we must call the <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
+        member function on the io_context object.
+      </p>
+<p>
+        The asio library provides a guarantee that completion handlers will only
+        be called from threads that are currently calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
+        Therefore unless the <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
+        function is called the completion handler for the asynchronous wait completion
+        will never be invoked.
+      </p>
+<p>
+        The <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
+        function will also continue to run while there is still "work"
+        to do. In this example, the work is the asynchronous wait on the timer, so
+        the call will not return until the timer has expired and the completion handler
+        has returned.
+      </p>
+<p>
+        It is important to remember to give the io_context some work to do before
+        calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
+        For example, if we had omitted the above call to <a class="link" href="../reference/basic_waitable_timer/async_wait.html" title="basic_waitable_timer::async_wait">steady_timer::async_wait()</a>,
+        the io_context would not have had any work to do, and consequently <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a> would have
+        returned immediately.

+<p>
+        To implement a repeating timer using asio you need to change the timer's
+        expiry time in your completion handler, and to then start a new asynchronous
+        wait. Obviously this means that the completion handler will need to be able
+        to access the timer object. To this end we add two new parameters to the
+        <code class="computeroutput"><span class="identifier">print</span></code> function:
+      </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+            a pointer to a timer object; and
+          </li>
+<li class="listitem">
+            a counter so that we can stop the program when the timer fires for the
+            sixth time
+          </li>
+</ul></div>
+<p>
+        at the end of the parameter list.
+      </p>
+<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">print</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span><span class="special">&amp;</span> <span class="comment">/*e*/</span><span class="special">,</span>

+</pre>
+<p>
+        As mentioned above, this tutorial program uses a counter to stop running
+        when the timer fires for the sixth time. However you will observe that there
+        is no explicit call to ask the io_context to stop. Recall that in tutorial
+        Timer.2 we learnt that the <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
+        function completes when there is no more "work" to do. By not starting
+        a new asynchronous wait on the timer when <code class="computeroutput"><span class="identifier">count</span></code>
+        reaches 5, the io_context will run out of work and stop running.
+      </p>
+<pre class="programlisting">  <span class="keyword">if</span> <span class="special">(*</span><span class="identifier">count</span> <span class="special">&lt;</span> <span class="number">5</span><span class="special">)</span>
+  <span class="special">{</span>
+    <span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span> <span class="special">&lt;&lt;</span> <span class="special">*</span><span class="identifier">count</span> <span class="special">&lt;&lt;</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">endl</span><span class="special">;</span>
+    <span class="special">++(*</span><span class="identifier">count</span><span class="special">);</span>
+</pre>
+<p>
+        Next we move the expiry time for the timer along by one second from the previous
+        expiry time. By calculating the new expiry time relative to the old, we can
+        ensure that the timer does not drift away from the whole-second mark due
+        to any delays in processing the handler.
+      </p>
+<pre class="programlisting">    <span class="identifier">t</span><span class="special">-&gt;</span><span class="identifier">expires_at</span><span class="special">(</span><span class="identifier">t</span><span class="special">-&gt;</span><span class="identifier">expiry</span><span class="special">()</span> <span class="special">+</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">chrono</span><span class="special">::</span><span class="identifier">seconds</span><span class="special">(</span><span class="number">1</span><span class="special">));</span>
+</pre>
+<p>
+        Then we start a new asynchronous wait on the timer. As you can see, the
+        <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a> function is used
+        to associate the extra parameters with your completion handler. The <a class="link" href="../reference/basic_waitable_timer/async_wait.html" title="basic_waitable_timer::async_wait">steady_timer::async_wait()</a>
+        function expects a handler function (or function object) with the signature
+        <code class="computeroutput"><span class="keyword">void</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span><span class="special">&amp;)</span></code>. Binding the additional parameters
+        converts your <code class="computeroutput"><span class="identifier">print</span></code> function
+        into a function object that matches the signature correctly.
+      </p>
+<p>
+        See the <a href="http://www.boost.org/libs/bind/bind.html" target="_top">Boost.Bind
+        documentation</a> for more information on how to use <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a>.
+      </p>
+<p>
+        In this example, the asio::placeholders::error argument to <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a>
+        is a named placeholder for the error object passed to the handler. When initiating
+        the asynchronous operation, and if using <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a>,
+        you must specify only the arguments that match the handler's parameter list.
+        In tutorial Timer.4 you will see that this placeholder may be elided if the
+        parameter is not needed by the completion handler.

+<p>
+        In this tutorial we will see how to use a class member function as a completion
+        handler. The program should execute identically to the tutorial program from
+        tutorial Timer.3.
+      </p>

+</pre>
+<p>
+        Instead of defining a free function <code class="computeroutput"><span class="identifier">print</span></code>
+        as the completion handler, as we did in the earlier tutorial programs, we
+        now define a class called <code class="computeroutput"><span class="identifier">printer</span></code>.
+      </p>
+<pre class="programlisting"><span class="keyword">class</span> <span class="identifier">printer</span>
+<span class="special">{</span>
+<span class="keyword">public</span><span class="special">:</span>
+</pre>
+<p>
+        The constructor of this class will take a reference to the io_context object
+        and use it when initialising the <code class="computeroutput"><span class="identifier">timer_</span></code>
+        member. The counter used to shut down the program is now also a member of
+        the class.
+      </p>
+<pre class="programlisting">  <span class="identifier">printer</span><span class="special">(</span><span class="identifier">asio</span><span class="special">::</span><span class="identifier">io_context</span><span class="special">&amp;</span> <span class="identifier">io</span><span class="special">)</span>

+  <span class="special">{</span>
+</pre>
+<p>
+        The <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a> function
+        works just as well with class member functions as with free functions. Since
+        all non-static class member functions have an implicit <code class="computeroutput"><span class="keyword">this</span></code>
+        parameter, we need to bind <code class="computeroutput"><span class="keyword">this</span></code>
+        to the function. As in tutorial Timer.3, <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a>
+        converts our completion handler (now a member function) into a function object
+        that can be invoked as though it has the signature <code class="computeroutput"><span class="keyword">void</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span><span class="special">&amp;)</span></code>.
+      </p>
+<p>
+        You will note that the asio::placeholders::error placeholder is not specified
+        here, as the <code class="computeroutput"><span class="identifier">print</span></code> member
+        function does not accept an error object as a parameter.
+      </p>
+<pre class="programlisting">    <span class="identifier">timer_</span><span class="special">.</span><span class="identifier">async_wait</span><span class="special">(</span><span class="identifier">boost</span><span class="special">::</span><span class="identifier">bind</span><span class="special">(&amp;</span><span class="identifier">printer</span><span class="special">::</span><span class="identifier">print</span><span class="special">,</span> <span class="keyword">this</span><span class="special">));</span>
+  <span class="special">}</span>
+</pre>
+<p>
+        In the class destructor we will print out the final value of the counter.

+<p>
+        The <code class="computeroutput"><span class="identifier">print</span></code> member function
+        is very similar to the <code class="computeroutput"><span class="identifier">print</span></code>
+        function from tutorial Timer.3, except that it now operates on the class
+        data members instead of having the timer and counter passed in as parameters.

+</h3></div></div></div>
+<p>
+        This tutorial demonstrates the use of the <a class="link" href="../reference/strand.html" title="strand">strand</a>
+        class template to synchronise completion handlers in a multithreaded program.
+      </p>
+<p>
+        The previous four tutorials avoided the issue of handler synchronisation
+        by calling the <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
+        function from one thread only. As you already know, the asio library provides
+        a guarantee that completion handlers will only be called from threads that
+        are currently calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
+        Consequently, calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
+        from only one thread ensures that completion handlers cannot run concurrently.
+      </p>
+<p>
+        The single threaded approach is usually the best place to start when developing
+        applications using asio. The downside is the limitations it places on programs,
+        particularly servers, including:
+      </p>
+<div class="itemizedlist"><ul class="itemizedlist" type="disc">
+<li class="listitem">
+            Poor responsiveness when handlers can take a long time to complete.
+          </li>
+<li class="listitem">
+            An inability to scale on multiprocessor systems.
+          </li>
+</ul></div>
+<p>
+        If you find yourself running into these limitations, an alternative approach
+        is to have a pool of threads calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
+        However, as this allows handlers to execute concurrently, we need a method
+        of synchronisation when handlers might be accessing a shared, thread-unsafe
+        resource.
+      </p>

+</pre>
+<p>
+        We start by defining a class called <code class="computeroutput"><span class="identifier">printer</span></code>,
+        similar to the class in the previous tutorial. This class will extend the
+        previous tutorial by running two timers in parallel.
+      </p>

+<span class="keyword">public</span><span class="special">:</span>
+</pre>
+<p>
+        In addition to initialising a pair of asio::steady_timer members, the constructor
+        initialises the <code class="computeroutput"><span class="identifier">strand_</span></code> member,
+        an object of type asio::strand&lt;asio::io_context::executor_type&gt;.
+      </p>
+<p>
+        The <a class="link" href="../reference/strand.html" title="strand">strand</a> class template is
+        an executor adapter that guarantees that, for those handlers that are dispatched
+        through it, an executing handler will be allowed to complete before the next
+        one is started. This is guaranteed irrespective of the number of threads
+        that are calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
+        Of course, the handlers may still execute concurrently with other handlers
+        that were not dispatched through an <a class="link" href="../reference/strand.html" title="strand">strand</a>,
+        or were dispatched through a different <a class="link" href="../reference/strand.html" title="strand">strand</a>

+<p>
+        When initiating the asynchronous operations, each completion handler is "bound"
+        to an asio::strand&lt;asio::io_context::executor_type&gt; object. The asio::bind_executor()
+        function returns a new handler that automatically dispatches its contained
+        handler through the <a class="link" href="../reference/strand.html" title="strand">strand</a> object.
+        By binding the handlers to the same <a class="link" href="../reference/strand.html" title="strand">strand</a>,
+        we are ensuring that they cannot execute concurrently.

+      By default, Asio is a header-only library. However, some developers may prefer

+      project/compiler settings. Alternatively, <code class="computeroutput"><span class="identifier">ASIO_DYN_LINK</span></code>
+      may be defined to build a separately-compiled Asio as part of a shared library.
+    </p>
+<p>
+      If using Asio's SSL support, you will also need to add <code class="computeroutput"><span class="preprocessor">#include</span>

+      If the boost directory (e.g. the directory called <code class="computeroutput"><span class="identifier">boost_1_34_1</span></code>)
+      is in the same directory as the asio source kit, then you may configure asio
+      by simply going:

+<pre class="programlisting"><span class="special">./</span><span class="identifier">configure</span>
+</pre>
+<p>
+      in the root directory of the asio source kit. Note that configure will always
+      use the most recent boost version it knows about (i.e. 1.34.1) in preference
+      to earlier versions, if there is more than one version present.
+    </p>
+<p>
+      If the boost directory is in some other location, then you need to specify
+      this directory when running configure:

+      When specifying the boost directory in this way you should ensure that you

+<p>
+      To build the examples, simply run <code class="computeroutput"><span class="identifier">make</span></code>

+      Asio automatically defines preprocessor macros corresponding to the detected
+      available features on a particular compiler and target platform. These macros
+      are named with the prefix <code class="computeroutput"><span class="identifier">ASIO_HAS_</span></code>,
+      and are listed in the table below.
+    </p>
+<p>
+      Many of these macros also have a corresponding <code class="computeroutput"><span class="identifier">ASIO_DISABLE_</span></code>
+      macro that may be used to explicitly disable the feature.
+    </p>
+<p>
+      In general, <code class="computeroutput"><span class="identifier">ASIO_HAS_</span></code> macros
+      should not be explicitly defined by the user, except when absolutely required
+      as a workaround for the latest version of a compiler or platform. For older
+      compiler/platform combinations where a specific <code class="computeroutput"><span class="identifier">ASIO_HAS_</span></code>
+      macro is not automatically defined, testing may have shown that a claimed feature
+      isn't sufficiently conformant to be compatible with Asio's needs.

+
+/// Provides waitable timer functionality.
+/**
+ * The basic_deadline_timer class template provides the ability to perform a
+ * blocking or asynchronous wait for a timer to expire.
+ *
+ * A deadline timer is always in one of two states: "expired" or "not expired".
+ * If the wait() or async_wait() function is called on an expired timer, the
+ * wait operation will complete immediately.
+ *
+ * Most applications will use the asio::deadline_timer typedef.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Examples
+ * Performing a blocking wait:
+ * @code
+ * // Construct a timer without setting an expiry time.
+ * asio::deadline_timer timer(my_context);
+ *
+ * // Set an expiry time relative to now.
+ * timer.expires_from_now(boost::posix_time::seconds(5));
+ *
+ * // Wait for the timer to expire.
+ * timer.wait();
+ * @endcode
+ *
+ * @par 
+ * Performing an asynchronous wait:
+ * @code
+ * void handler(const asio::error_code& error)
+ * {
+ *   if (!error)
+ *   {
+ *     // Timer expired.
+ *   }
+ * }
+ *
+ * ...
+ *
+ * // Construct a timer with an absolute expiry time.
+ * asio::deadline_timer timer(my_context,
+ *     boost::posix_time::time_from_string("2005-12-07 23:59:59.000"));
+ *
+ * // Start an asynchronous wait.
+ * timer.async_wait(handler);
+ * @endcode
+ *
+ * @par Changing an active deadline_timer's expiry time
+ *
+ * Changing the expiry time of a timer while there are pending asynchronous
+ * waits causes those wait operations to be cancelled. To ensure that the action
+ * associated with the timer is performed only once, use something like this:
+ * used:
+ *
+ * @code
+ * void on_some_event()
+ * {
+ *   if (my_timer.expires_from_now(seconds(5)) > 0)
+ *   {
+ *     // We managed to cancel the timer. Start new asynchronous wait.
+ *     my_timer.async_wait(on_timeout);
+ *   }
+ *   else
+ *   {
+ *     // Too late, timer has already expired!
+ *   }
+ * }
+ *
+ * void on_timeout(const asio::error_code& e)
+ * {
+ *   if (e != asio::error::operation_aborted)
+ *   {
+ *     // Timer was not cancelled, take necessary action.
+ *   }
+ * }
+ * @endcode
+ *
+ * @li The asio::basic_deadline_timer::expires_from_now() function
+ * cancels any pending asynchronous waits, and returns the number of
+ * asynchronous waits that were cancelled. If it returns 0 then you were too
+ * late and the wait handler has already been executed, or will soon be
+ * executed. If it returns 1 then the wait handler was successfully cancelled.
+ *
+ * @li If a wait handler is cancelled, the asio::error_code passed to
+ * it contains the value asio::error::operation_aborted.

+  /**
+   * This function is used to asynchronously receive data from the sequenced
+   * data socket. It is an initiating function for an @ref
+   * asynchronous_operation, and always returns immediately.
+   *
+   * @param buffers One or more buffers into which the data will be received.
+   * Although the buffers object may be copied as necessary, ownership of the
+   * underlying memory blocks is retained by the caller, which must guarantee
+   * that they remain valid until the completion handler is called.
+   *
+   * @param in_flags Flags specifying how the receive call is to be made.
+   *
+   * @param out_flags Once the asynchronous operation completes, contains flags
+   * associated with the received data. For example, if the
+   * socket_base::message_end_of_record bit is set then the received data marks
+   * the end of a record. The caller must guarantee that the referenced
+   * variable remains valid until the completion handler is called.
+   *
+   * @param token The @ref completion_token that will be used to produce a
+   * completion handler, which will be called when the receive completes.
+   * Potential completion tokens include @ref use_future, @ref use_awaitable,
+   * @ref yield_context, or a function object with the correct completion
+   * signature. The function signature of the completion handler must be:
+   * @code void handler(
+   *   const asio::error_code& error, // Result of operation.
+   *   std::size_t bytes_transferred // Number of bytes received.
+   * ); @endcode
+   * Regardless of whether the asynchronous operation completes immediately or
+   * not, the completion handler will not be invoked from within this function.
+   * On immediate completion, invocation of the handler will be performed in a
+   * manner equivalent to using asio::post().
+   *
+   * @par Completion Signature
+   * @code void(asio::error_code, std::size_t) @endcode
+   *
+   * @par Example
+   * To receive into a single data buffer use the @ref buffer function as
+   * follows:
+   * @code
+   * socket.async_receive(
+   *     asio::buffer(data, size),
+   *     0, out_flags, handler);
+   * @endcode
+   * See the @ref buffer documentation for information on receiving into
+   * multiple buffers in one go, and how to use it with arrays, boost::array or
+   * std::vector.
+   *
+   * @par Per-Operation Cancellation
+   * On POSIX or Windows operating systems, this asynchronous operation supports
+   * cancellation for the following asio::cancellation_type values:
+   *
+   * @li @c cancellation_type::terminal
+   *
+   * @li @c cancellation_type::partial
+   *
+   * @li @c cancellation_type::total

+ * The basic_signal_set class provides the ability to perform an asynchronous
+ * wait for one or more signals to occur.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Example
+ * Performing an asynchronous wait:
+ * @code
+ * void handler(
+ *     const asio::error_code& error,
+ *     int signal_number)
+ * {
+ *   if (!error)
+ *   {
+ *     // A signal occurred.
+ *   }
+ * }
+ *
+ * ...
+ *
+ * // Construct a signal set registered for process termination.
+ * asio::signal_set signals(my_context, SIGINT, SIGTERM);
+ *
+ * // Start an asynchronous wait for one of the signals to occur.
+ * signals.async_wait(handler);
+ * @endcode
+ *
+ * @par Queueing of signal notifications
+ *
+ * If a signal is registered with a signal_set, and the signal occurs when
+ * there are no waiting handlers, then the signal notification is queued. The
+ * next async_wait operation on that signal_set will dequeue the notification.
+ * If multiple notifications are queued, subsequent async_wait operations
+ * dequeue them one at a time. Signal notifications are dequeued in order of
+ * ascending signal number.
+ *
+ * If a signal number is removed from a signal_set (using the @c remove or @c
+ * erase member functions) then any queued notifications for that signal are
+ * discarded.
+ *
+ * @par Multiple registration of signals
+ *
+ * The same signal number may be registered with different signal_set objects.
+ * When the signal occurs, one handler is called for each signal_set object.
+ *
+ * Note that multiple registration only works for signals that are registered
+ * using Asio. The application must not also register a signal handler using
+ * functions such as @c signal() or @c sigaction().
+ *
+ * @par Signal masking on POSIX platforms
+ *
+ * POSIX allows signals to be blocked using functions such as @c sigprocmask()
+ * and @c pthread_sigmask(). For signals to be delivered, programs must ensure
+ * that any signals registered using signal_set objects are unblocked in at
+ * least one thread.

+ * The basic_socket_acceptor class template is used for accepting new socket

+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * Synchronous @c accept operations are thread safe, if the underlying
+ * operating system calls are also thread safe. This means that it is permitted
+ * to perform concurrent calls to synchronous @c accept operations on a single
+ * socket object. Other synchronous operations, such as @c open or @c close, are
+ * not thread safe.
+ *
+ * @par Example
+ * Opening a socket acceptor with the SO_REUSEADDR option enabled:
+ * @code
+ * asio::ip::tcp::acceptor acceptor(my_context);
+ * asio::ip::tcp::endpoint endpoint(asio::ip::tcp::v4(), port);
+ * acceptor.open(endpoint.protocol());
+ * acceptor.set_option(asio::ip::tcp::acceptor::reuse_address(true));
+ * acceptor.bind(endpoint);

+/// Automatically resizable buffer class based on std::streambuf.
+/**
+ * The @c basic_streambuf class is derived from @c std::streambuf to associate
+ * the streambuf's input and output sequences with one or more character
+ * arrays. These character arrays are internal to the @c basic_streambuf
+ * object, but direct access to the array elements is provided to permit them
+ * to be used efficiently with I/O operations. Characters written to the output
+ * sequence of a @c basic_streambuf object are appended to the input sequence
+ * of the same object.
+ *
+ * The @c basic_streambuf class's public interface is intended to permit the
+ * following implementation strategies:
+ *
+ * @li A single contiguous character array, which is reallocated as necessary
+ * to accommodate changes in the size of the character sequence. This is the
+ * implementation approach currently used in Asio.
+ *
+ * @li A sequence of one or more character arrays, where each array is of the
+ * same size. Additional character array objects are appended to the sequence
+ * to accommodate changes in the size of the character sequence.
+ *
+ * @li A sequence of one or more character arrays of varying sizes. Additional
+ * character array objects are appended to the sequence to accommodate changes
+ * in the size of the character sequence.
+ *
+ * The constructor for basic_streambuf accepts a @c size_t argument specifying
+ * the maximum of the sum of the sizes of the input sequence and output
+ * sequence. During the lifetime of the @c basic_streambuf object, the following
+ * invariant holds:
+ * @code size() <= max_size()@endcode
+ * Any member function that would, if successful, cause the invariant to be
+ * violated shall throw an exception of class @c std::length_error.
+ *
+ * The constructor for @c basic_streambuf takes an Allocator argument. A copy
+ * of this argument is used for any memory allocation performed, by the
+ * constructor and by all member functions, during the lifetime of each @c
+ * basic_streambuf object.
+ *
+ * @par Examples
+ * Writing directly from an streambuf to a socket:
+ * @code
+ * asio::streambuf b;
+ * std::ostream os(&b);
+ * os << "Hello, World!\n";
+ *
+ * // try sending some data in input sequence
+ * size_t n = sock.send(b.data());
+ *
+ * b.consume(n); // sent data is removed from input sequence
+ * @endcode
+ *
+ * Reading from a socket directly into a streambuf:
+ * @code
+ * asio::streambuf b;
+ *
+ * // reserve 512 bytes in output sequence
+ * asio::streambuf::mutable_buffers_type bufs = b.prepare(512);
+ *
+ * size_t n = sock.receive(bufs);
+ *
+ * // received data is "committed" from output sequence to input sequence
+ * b.commit(n);
+ *
+ * std::istream is(&b);
+ * std::string s;
+ * is >> s;
+ * @endcode

+/// Provides waitable timer functionality.
+/**
+ * The basic_waitable_timer class template provides the ability to perform a
+ * blocking or asynchronous wait for a timer to expire.
+ *
+ * A waitable timer is always in one of two states: "expired" or "not expired".
+ * If the wait() or async_wait() function is called on an expired timer, the
+ * wait operation will complete immediately.
+ *
+ * Most applications will use one of the asio::steady_timer,
+ * asio::system_timer or asio::high_resolution_timer typedefs.
+ *
+ * @note This waitable timer functionality is for use with the C++11 standard
+ * library's @c &lt;chrono&gt; facility, or with the Boost.Chrono library.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Examples
+ * Performing a blocking wait (C++11):
+ * @code
+ * // Construct a timer without setting an expiry time.
+ * asio::steady_timer timer(my_context);
+ *
+ * // Set an expiry time relative to now.
+ * timer.expires_after(std::chrono::seconds(5));
+ *
+ * // Wait for the timer to expire.
+ * timer.wait();
+ * @endcode
+ *
+ * @par 
+ * Performing an asynchronous wait (C++11):
+ * @code
+ * void handler(const asio::error_code& error)
+ * {
+ *   if (!error)
+ *   {
+ *     // Timer expired.
+ *   }
+ * }
+ *
+ * ...
+ *
+ * // Construct a timer with an absolute expiry time.
+ * asio::steady_timer timer(my_context,
+ *     std::chrono::steady_clock::now() + std::chrono::seconds(60));
+ *
+ * // Start an asynchronous wait.
+ * timer.async_wait(handler);
+ * @endcode
+ *
+ * @par Changing an active waitable timer's expiry time
+ *
+ * Changing the expiry time of a timer while there are pending asynchronous
+ * waits causes those wait operations to be cancelled. To ensure that the action
+ * associated with the timer is performed only once, use something like this:
+ * used:
+ *
+ * @code
+ * void on_some_event()
+ * {
+ *   if (my_timer.expires_after(seconds(5)) > 0)
+ *   {
+ *     // We managed to cancel the timer. Start new asynchronous wait.
+ *     my_timer.async_wait(on_timeout);
+ *   }
+ *   else
+ *   {
+ *     // Too late, timer has already expired!
+ *   }
+ * }
+ *
+ * void on_timeout(const asio::error_code& e)
+ * {
+ *   if (e != asio::error::operation_aborted)
+ *   {
+ *     // Timer was not cancelled, take necessary action.
+ *   }
+ * }
+ * @endcode
+ *
+ * @li The asio::basic_waitable_timer::expires_after() function
+ * cancels any pending asynchronous waits, and returns the number of
+ * asynchronous waits that were cancelled. If it returns 0 then you were too
+ * late and the wait handler has already been executed, or will soon be
+ * executed. If it returns 1 then the wait handler was successfully cancelled.
+ *
+ * @li If a wait handler is cancelled, the asio::error_code passed to
+ * it contains the value asio::error::operation_aborted.

+/** @defgroup buffer asio::buffer
+ *
+ * @brief The asio::buffer function is used to create a buffer object to
+ * represent raw memory, an array of POD elements, a vector of POD elements,
+ * or a std::string.
+ *
+ * A buffer object represents a contiguous region of memory as a 2-tuple
+ * consisting of a pointer and size in bytes. A tuple of the form <tt>{void*,
+ * size_t}</tt> specifies a mutable (modifiable) region of memory. Similarly, a
+ * tuple of the form <tt>{const void*, size_t}</tt> specifies a const
+ * (non-modifiable) region of memory. These two forms correspond to the classes
+ * mutable_buffer and const_buffer, respectively. To mirror C++'s conversion
+ * rules, a mutable_buffer is implicitly convertible to a const_buffer, and the
+ * opposite conversion is not permitted.
+ *
+ * The simplest use case involves reading or writing a single buffer of a
+ * specified size:
+ *
+ * @code sock.send(asio::buffer(data, size)); @endcode
+ *
+ * In the above example, the return value of asio::buffer meets the
+ * requirements of the ConstBufferSequence concept so that it may be directly
+ * passed to the socket's write function. A buffer created for modifiable
+ * memory also meets the requirements of the MutableBufferSequence concept.
+ *
+ * An individual buffer may be created from a builtin array, std::vector,
+ * std::array or boost::array of POD elements. This helps prevent buffer
+ * overruns by automatically determining the size of the buffer:
+ *
+ * @code char d1[128];
+ * size_t bytes_transferred = sock.receive(asio::buffer(d1));
+ *
+ * std::vector<char> d2(128);
+ * bytes_transferred = sock.receive(asio::buffer(d2));
+ *
+ * std::array<char, 128> d3;
+ * bytes_transferred = sock.receive(asio::buffer(d3));
+ *
+ * boost::array<char, 128> d4;
+ * bytes_transferred = sock.receive(asio::buffer(d4)); @endcode
+ *
+ * In all three cases above, the buffers created are exactly 128 bytes long.
+ * Note that a vector is @e never automatically resized when creating or using
+ * a buffer. The buffer size is determined using the vector's <tt>size()</tt>
+ * member function, and not its capacity.
+ *
+ * @par Accessing Buffer Contents
+ *
+ * The contents of a buffer may be accessed using the @c data() and @c size()
+ * member functions:
+ *
+ * @code asio::mutable_buffer b1 = ...;
+ * std::size_t s1 = b1.size();
+ * unsigned char* p1 = static_cast<unsigned char*>(b1.data());
+ *
+ * asio::const_buffer b2 = ...;
+ * std::size_t s2 = b2.size();
+ * const void* p2 = b2.data(); @endcode
+ *
+ * The @c data() member function permits violations of type safety, so
+ * uses of it in application code should be carefully considered.
+ *
+ * For convenience, a @ref buffer_size function is provided that works with
+ * both buffers and buffer sequences (that is, types meeting the
+ * ConstBufferSequence or MutableBufferSequence type requirements). In this
+ * case, the function returns the total size of all buffers in the sequence.
+ *
+ * @par Buffer Copying
+ *
+ * The @ref buffer_copy function may be used to copy raw bytes between
+ * individual buffers and buffer sequences.
+*
+ * In particular, when used with the @ref buffer_size function, the @ref
+ * buffer_copy function can be used to linearise a sequence of buffers. For
+ * example:
+ *
+ * @code vector<const_buffer> buffers = ...;
+ *
+ * vector<unsigned char> data(asio::buffer_size(buffers));
+ * asio::buffer_copy(asio::buffer(data), buffers); @endcode
+ *
+ * Note that @ref buffer_copy is implemented in terms of @c memcpy, and
+ * consequently it cannot be used to copy between overlapping memory regions.
+ *
+ * @par Buffer Invalidation
+ *
+ * A buffer object does not have any ownership of the memory it refers to. It
+ * is the responsibility of the application to ensure the memory region remains
+ * valid until it is no longer required for an I/O operation. When the memory
+ * is no longer available, the buffer is said to have been invalidated.
+ *
+ * For the asio::buffer overloads that accept an argument of type
+ * std::vector, the buffer objects returned are invalidated by any vector
+ * operation that also invalidates all references, pointers and iterators
+ * referring to the elements in the sequence (C++ Std, 23.2.4)
+ *
+ * For the asio::buffer overloads that accept an argument of type
+ * std::basic_string, the buffer objects returned are invalidated according to
+ * the rules defined for invalidation of references, pointers and iterators
+ * referring to elements of the sequence (C++ Std, 21.3).
+ *
+ * @par Buffer Arithmetic
+ *
+ * Buffer objects may be manipulated using simple arithmetic in a safe way
+ * which helps prevent buffer overruns. Consider an array initialised as
+ * follows:
+ *
+ * @code boost::array<char, 6> a = { 'a', 'b', 'c', 'd', 'e' }; @endcode
+ *
+ * A buffer object @c b1 created using:
+ *
+ * @code b1 = asio::buffer(a); @endcode
+ *
+ * represents the entire array, <tt>{ 'a', 'b', 'c', 'd', 'e' }</tt>. An
+ * optional second argument to the asio::buffer function may be used to
+ * limit the size, in bytes, of the buffer:
+ *
+ * @code b2 = asio::buffer(a, 3); @endcode
+ *
+ * such that @c b2 represents the data <tt>{ 'a', 'b', 'c' }</tt>. Even if the
+ * size argument exceeds the actual size of the array, the size of the buffer
+ * object created will be limited to the array size.
+ *
+ * An offset may be applied to an existing buffer to create a new one:
+ *
+ * @code b3 = b1 + 2; @endcode
+ *
+ * where @c b3 will set to represent <tt>{ 'c', 'd', 'e' }</tt>. If the offset
+ * exceeds the size of the existing buffer, the newly created buffer will be
+ * empty.
+ *
+ * Both an offset and size may be specified to create a buffer that corresponds
+ * to a specific range of bytes within an existing buffer:
+ *
+ * @code b4 = asio::buffer(b1 + 1, 3); @endcode
+ *
+ * so that @c b4 will refer to the bytes <tt>{ 'b', 'c', 'd' }</tt>.
+ *
+ * @par Buffers and Scatter-Gather I/O
+ *
+ * To read or write using multiple buffers (i.e. scatter-gather I/O), multiple
+ * buffer objects may be assigned into a container that supports the
+ * MutableBufferSequence (for read) or ConstBufferSequence (for write) concepts:
+ *
+ * @code
+ * char d1[128];
+ * std::vector<char> d2(128);
+ * boost::array<char, 128> d3;
+ *
+ * boost::array<mutable_buffer, 3> bufs1 = {
+ *   asio::buffer(d1),
+ *   asio::buffer(d2),
+ *   asio::buffer(d3) };
+ * bytes_transferred = sock.receive(bufs1);
+ *
+ * std::vector<const_buffer> bufs2;
+ * bufs2.push_back(asio::buffer(d1));
+ * bufs2.push_back(asio::buffer(d2));
+ * bufs2.push_back(asio::buffer(d3));
+ * bytes_transferred = sock.send(bufs2); @endcode
+ *
+ * @par Buffer Literals
+ *
+ * The `_buf` literal suffix, defined in namespace
+ * <tt>asio::buffer_literals</tt>, may be used to create @c const_buffer
+ * objects from string, binary integer, and hexadecimal integer literals.
+ * For example:
+ *
+ * @code
+ * using namespace asio::buffer_literals;
+ *
+ * asio::const_buffer b1 = "hello"_buf;
+ * asio::const_buffer b2 = 0xdeadbeef_buf;
+ * asio::const_buffer b3 = 0x0123456789abcdef0123456789abcdef_buf;
+ * asio::const_buffer b4 = 0b1010101011001100_buf; @endcode
+ *
+ * Note that the memory associated with a buffer literal is valid for the
+ * lifetime of the program. This means that the buffer can be safely used with
+ * asynchronous operations.

+ * is successfully established. It is an initiating function for an @ref
+ * asynchronous_operation, and always returns immediately.
+ *
+ * @param s The socket to be connected. If the socket is already open, it will
+ * be closed.
+ *
+ * @param endpoints A sequence of endpoints.
+ *
+ * @param connect_condition A function object that is called prior to each
+ * connection attempt. The signature of the function object must be:
+ * @code bool connect_condition(
+ *     const asio::error_code& ec,
+ *     const typename Protocol::endpoint& next); @endcode
+ * The @c ec parameter contains the result from the most recent connect
+ * operation. Before the first connection attempt, @c ec is always set to
+ * indicate success. The @c next parameter is the next endpoint to be tried.
+ * The function object should return true if the next endpoint should be tried,
+ * and false if it should be skipped.
+ *
+ * @param token The @ref completion_token that will be used to produce a
+ * completion handler, which will be called when the connect completes.
+ * Potential completion tokens include @ref use_future, @ref use_awaitable,
+ * @ref yield_context, or a function object with the correct completion
+ * signature. The function signature of the completion handler must be:
+ * @code void handler(
+ *   // Result of operation. if the sequence is empty, set to
+ *   // asio::error::not_found. Otherwise, contains the
+ *   // error from the last connection attempt.
+ *   const asio::error_code& error,
+ *
+ *   // On success, an iterator denoting the successfully
+ *   // connected endpoint. Otherwise, the end iterator.
+ *   Iterator iterator
+ * ); @endcode
+ * Regardless of whether the asynchronous operation completes immediately or
+ * not, the completion handler will not be invoked from within this function.
+ * On immediate completion, invocation of the handler will be performed in a
+ * manner equivalent to using asio::post().
+ *
+ * @par Completion Signature
+ * @code void(asio::error_code, typename Protocol::endpoint) @endcode
+ *
+ * @par Example
+ * The following connect condition function object can be used to output
+ * information about the individual connection attempts:
+ * @code struct my_connect_condition
+ * {
+ *   bool operator()(
+ *       const asio::error_code& ec,
+ *       const::tcp::endpoint& next)
+ *   {
+ *     if (ec) std::cout << "Error: " << ec.message() << std::endl;
+ *     std::cout << "Trying: " << next << std::endl;
+ *     return true;
+ *   }
+ * }; @endcode
+ * It would be used with the asio::connect function as follows:
+ * @code tcp::resolver r(my_context);
+ * tcp::resolver::query q("host", "service");
+ * tcp::socket s(my_context);
+ *
+ * // ...
+ *
+ * r.async_resolve(q, resolve_handler);
+ *
+ * // ...
+ *
+ * void resolve_handler(
+ *     const asio::error_code& ec,
+ *     tcp::resolver::results_type results)
+ * {
+ *   if (!ec)
+ *   {
+ *     asio::async_connect(s, results,

+/// Provides support for implementing stackless coroutines.
+/**
+ * The @c coroutine class may be used to implement stackless coroutines. The
+ * class itself is used to store the current state of the coroutine.
+ *
+ * Coroutines are copy-constructible and assignable, and the space overhead is
+ * a single int. They can be used as a base class:
+ *
+ * @code class session : coroutine
+ * {
+ *   ...
+ * }; @endcode
+ *
+ * or as a data member:
+ *
+ * @code class session
+ * {
+ *   ...
+ *   coroutine coro_;
+ * }; @endcode
+ *
+ * or even bound in as a function argument using lambdas or @c bind(). The
+ * important thing is that as the application maintains a copy of the object
+ * for as long as the coroutine must be kept alive.
+ *
+ * @par Pseudo-keywords
+ *
+ * A coroutine is used in conjunction with certain "pseudo-keywords", which
+ * are implemented as macros. These macros are defined by a header file:
+ *
+ * @code #include <asio/yield.hpp>@endcode
+ *
+ * and may conversely be undefined as follows:
+ *
+ * @code #include <asio/unyield.hpp>@endcode
+ *
+ * <b>reenter</b>
+ *
+ * The @c reenter macro is used to define the body of a coroutine. It takes a
+ * single argument: a pointer or reference to a coroutine object. For example,
+ * if the base class is a coroutine object you may write:
+ *
+ * @code reenter (this)
+ * {
+ *   ... coroutine body ...
+ * } @endcode
+ *
+ * and if a data member or other variable you can write:
+ *
+ * @code reenter (coro_)
+ * {
+ *   ... coroutine body ...
+ * } @endcode
+ *
+ * When @c reenter is executed at runtime, control jumps to the location of the
+ * last @c yield or @c fork.
+ *
+ * The coroutine body may also be a single statement, such as:
+ *
+ * @code reenter (this) for (;;)
+ * {
+ *   ...
+ * } @endcode
+ *
+ * @b Limitation: The @c reenter macro is implemented using a switch. This
+ * means that you must take care when using local variables within the
+ * coroutine body. The local variable is not allowed in a position where
+ * reentering the coroutine could bypass the variable definition.
+ *
+ * <b>yield <em>statement</em></b>
+ *
+ * This form of the @c yield keyword is often used with asynchronous operations:
+ *
+ * @code yield socket_->async_read_some(buffer(*buffer_), *this); @endcode
+ *
+ * This divides into four logical steps:
+ *
+ * @li @c yield saves the current state of the coroutine.
+ * @li The statement initiates the asynchronous operation.
+ * @li The resume point is defined immediately following the statement.
+ * @li Control is transferred to the end of the coroutine body.
+ *
+ * When the asynchronous operation completes, the function object is invoked
+ * and @c reenter causes control to transfer to the resume point. It is
+ * important to remember to carry the coroutine state forward with the
+ * asynchronous operation. In the above snippet, the current class is a
+ * function object object with a coroutine object as base class or data member.
+ *
+ * The statement may also be a compound statement, and this permits us to
+ * define local variables with limited scope:
+ *
+ * @code yield
+ * {
+ *   mutable_buffers_1 b = buffer(*buffer_);
+ *   socket_->async_read_some(b, *this);
+ * } @endcode
+ *
+ * <b>yield return <em>expression</em> ;</b>
+ *
+ * This form of @c yield is often used in generators or coroutine-based parsers.
+ * For example, the function object:
+ *
+ * @code struct interleave : coroutine
+ * {
+ *   istream& is1;
+ *   istream& is2;
+ *   char operator()(char c)
+ *   {
+ *     reenter (this) for (;;)
+ *     {
+ *       yield return is1.get();
+ *       yield return is2.get();
+ *     }
+ *   }
+ * }; @endcode
+ *
+ * defines a trivial coroutine that interleaves the characters from two input
+ * streams.
+ *
+ * This type of @c yield divides into three logical steps:
+ *
+ * @li @c yield saves the current state of the coroutine.
+ * @li The resume point is defined immediately following the semicolon.
+ * @li The value of the expression is returned from the function.
+ *
+ * <b>yield ;</b>
+ *
+ * This form of @c yield is equivalent to the following steps:
+ *
+ * @li @c yield saves the current state of the coroutine.
+ * @li The resume point is defined immediately following the semicolon.
+ * @li Control is transferred to the end of the coroutine body.
+ *
+ * This form might be applied when coroutines are used for cooperative
+ * threading and scheduling is explicitly managed. For example:
+ *
+ * @code struct task : coroutine
+ * {
+ *   ...
+ *   void operator()()
+ *   {
+ *     reenter (this)
+ *     {
+ *       while (... not finished ...)
+ *       {
+ *         ... do something ...
+ *         yield;
+ *         ... do some more ...
+ *         yield;
+ *       }
+ *     }
+ *   }
+ *   ...
+ * };
+ * ...
+ * task t1, t2;
+ * for (;;)
+ * {
+ *   t1();
+ *   t2();
+ * } @endcode
+ *
+ * <b>yield break ;</b>
+ *
+ * The final form of @c yield is used to explicitly terminate the coroutine.
+ * This form is comprised of two steps:
+ *
+ * @li @c yield sets the coroutine state to indicate termination.
+ * @li Control is transferred to the end of the coroutine body.
+ *
+ * Once terminated, calls to is_complete() return true and the coroutine cannot
+ * be reentered.
+ *
+ * Note that a coroutine may also be implicitly terminated if the coroutine
+ * body is exited without a yield, e.g. by return, throw or by running to the
+ * end of the body.
+ *
+ * <b>fork <em>statement</em></b>
+ *
+ * The @c fork pseudo-keyword is used when "forking" a coroutine, i.e. splitting
+ * it into two (or more) copies. One use of @c fork is in a server, where a new
+ * coroutine is created to handle each client connection:
+ * 
+ * @code reenter (this)
+ * {
+ *   do
+ *   {
+ *     socket_.reset(new tcp::socket(my_context_));
+ *     yield acceptor->async_accept(*socket_, *this);
+ *     fork server(*this)();
+ *   } while (is_parent());
+ *   ... client-specific handling follows ...
+ * } @endcode
+ * 
+ * The logical steps involved in a @c fork are:
+ * 
+ * @li @c fork saves the current state of the coroutine.
+ * @li The statement creates a copy of the coroutine and either executes it
+ *     immediately or schedules it for later execution.
+ * @li The resume point is defined immediately following the semicolon.
+ * @li For the "parent", control immediately continues from the next line.
+ *
+ * The functions is_parent() and is_child() can be used to differentiate
+ * between parent and child. You would use these functions to alter subsequent
+ * control flow.
+ *
+ * Note that @c fork doesn't do the actual forking by itself. It is the
+ * application's responsibility to create a clone of the coroutine and call it.
+ * The clone can be called immediately, as above, or scheduled for delayed
+ * execution using something like asio::post().
+ *
+ * @par Alternate macro names
+ *
+ * If preferred, an application can use macro names that follow a more typical
+ * naming convention, rather than the pseudo-keywords. These are:
+ *
+ * @li @c ASIO_CORO_REENTER instead of @c reenter
+ * @li @c ASIO_CORO_YIELD instead of @c yield
+ * @li @c ASIO_CORO_FORK instead of @c fork

+/// A context for function object execution.
+/**
+ * An execution context represents a place where function objects will be
+ * executed. An @c io_context is an example of an execution context.
+ *
+ * @par The execution_context class and services
+ *
+ * Class execution_context implements an extensible, type-safe, polymorphic set
+ * of services, indexed by service type.
+ *
+ * Services exist to manage the resources that are shared across an execution
+ * context. For example, timers may be implemented in terms of a single timer
+ * queue, and this queue would be stored in a service.
+ *
+ * Access to the services of an execution_context is via three function
+ * templates, use_service(), add_service() and has_service().
+ *
+ * In a call to @c use_service<Service>(), the type argument chooses a service,
+ * making available all members of the named type. If @c Service is not present
+ * in an execution_context, an object of type @c Service is created and added
+ * to the execution_context. A C++ program can check if an execution_context
+ * implements a particular service with the function template @c
+ * has_service<Service>().
+ *
+ * Service objects may be explicitly added to an execution_context using the
+ * function template @c add_service<Service>(). If the @c Service is already
+ * present, the service_already_exists exception is thrown. If the owner of the
+ * service is not the same object as the execution_context parameter, the
+ * invalid_service_owner exception is thrown.
+ *
+ * Once a service reference is obtained from an execution_context object by
+ * calling use_service(), that reference remains usable as long as the owning
+ * execution_context object exists.
+ *
+ * All service implementations have execution_context::service as a public base
+ * class. Custom services may be implemented by deriving from this class and
+ * then added to an execution_context using the facilities described above.
+ *
+ * @par The execution_context as a base class
+ *
+ * Class execution_context may be used only as a base class for concrete
+ * execution context types. The @c io_context is an example of such a derived
+ * type.
+ *
+ * On destruction, a class that is derived from execution_context must perform
+ * <tt>execution_context::shutdown()</tt> followed by
+ * <tt>execution_context::destroy()</tt>.
+ *
+ * This destruction sequence permits programs to simplify their resource
+ * management by using @c shared_ptr<>. Where an object's lifetime is tied to
+ * the lifetime of a connection (or some other sequence of asynchronous
+ * operations), a @c shared_ptr to the object would be bound into the handlers
+ * for all asynchronous operations associated with it. This works as follows:
+ *
+ * @li When a single connection ends, all associated asynchronous operations
+ * complete. The corresponding handler objects are destroyed, and all @c
+ * shared_ptr references to the objects are destroyed.
+ *
+ * @li To shut down the whole program, the io_context function stop() is called
+ * to terminate any run() calls as soon as possible. The io_context destructor
+ * calls @c shutdown() and @c destroy() to destroy all pending handlers,
+ * causing all @c shared_ptr references to all connection objects to be
+ * destroyed.

+/// A channel for messages.
+/**
+ * The basic_channel class template is used for sending messages between
+ * different parts of the same application. A <em>message</em> is defined as a
+ * collection of arguments to be passed to a completion handler, and the set of
+ * messages supported by a channel is specified by its @c Traits and
+ * <tt>Signatures...</tt> template parameters. Messages may be sent and received
+ * using asynchronous or non-blocking synchronous operations.
+ *
+ * Unless customising the traits, applications will typically use the @c
+ * experimental::channel alias template. For example:
+ * @code void send_loop(int i, steady_timer& timer,
+ *     channel<void(error_code, int)>& ch)
+ * {
+ *   if (i < 10)
+ *   {
+ *     timer.expires_after(chrono::seconds(1));
+ *     timer.async_wait(
+ *         [i, &timer, &ch](error_code error)
+ *         {
+ *           if (!error)
+ *           {
+ *             ch.async_send(error_code(), i,
+ *                 [i, &timer, &ch](error_code error)
+ *                 {
+ *                   if (!error)
+ *                   {
+ *                     send_loop(i + 1, timer, ch);
+ *                   }
+ *                 });
+ *           }
+ *         });
+ *   }
+ *   else
+ *   {
+ *     ch.close();
+ *   }
+ * }
+ *
+ * void receive_loop(channel<void(error_code, int)>& ch)
+ * {
+ *   ch.async_receive(
+ *       [&ch](error_code error, int i)
+ *       {
+ *         if (!error)
+ *         {
+ *           std::cout << "Received " << i << "\n";
+ *           receive_loop(ch);
+ *         }
+ *       });
+ * } @endcode
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * The basic_channel class template is not thread-safe, and would typically be
+ * used for passing messages between application code that runs on the same
+ * thread or in the same strand. Consider using @ref basic_concurrent_channel,
+ * and its alias template @c experimental::concurrent_channel, to pass messages
+ * between code running in different threads.

+/// A channel for messages.
+/**
+ * The basic_concurrent_channel class template is used for sending messages
+ * between different parts of the same application. A <em>message</em> is
+ * defined as a collection of arguments to be passed to a completion handler,
+ * and the set of messages supported by a channel is specified by its @c Traits
+ * and <tt>Signatures...</tt> template parameters. Messages may be sent and
+ * received using asynchronous or non-blocking synchronous operations.
+ *
+ * Unless customising the traits, applications will typically use the @c
+ * experimental::concurrent_channel alias template. For example:
+ * @code void send_loop(int i, steady_timer& timer,
+ *     concurrent_channel<void(error_code, int)>& ch)
+ * {
+ *   if (i < 10)
+ *   {
+ *     timer.expires_after(chrono::seconds(1));
+ *     timer.async_wait(
+ *         [i, &timer, &ch](error_code error)
+ *         {
+ *           if (!error)
+ *           {
+ *             ch.async_send(error_code(), i,
+ *                 [i, &timer, &ch](error_code error)
+ *                 {
+ *                   if (!error)
+ *                   {
+ *                     send_loop(i + 1, timer, ch);
+ *                   }
+ *                 });
+ *           }
+ *         });
+ *   }
+ *   else
+ *   {
+ *     ch.close();
+ *   }
+ * }
+ *
+ * void receive_loop(concurent_channel<void(error_code, int)>& ch)
+ * {
+ *   ch.async_receive(
+ *       [&ch](error_code error, int i)
+ *       {
+ *         if (!error)
+ *         {
+ *           std::cout << "Received " << i << "\n";
+ *           receive_loop(ch);
+ *         }
+ *       });
+ * } @endcode
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Safe.
+ *
+ * The basic_concurrent_channel class template is thread-safe, and would
+ * typically be used for passing messages between application code that run on
+ * different threads. Consider using @ref basic_channel, and its alias template
+ * @c experimental::channel, to pass messages between code running in a single
+ * thread or on the same strand.

+/// Creates an initiation function object that may be used to launch a

+/**
+ * The experimental::co_composed utility simplifies the implementation of
+ * composed asynchronous operations by automatically adapting a coroutine to be
+ * an initiation function object for use with @c async_initiate. When awaiting
+ * asynchronous operations, the coroutine automatically uses a conforming
+ * intermediate completion handler.
+ *
+ * @param implementation A function object that contains the coroutine-based
+ * implementation of the composed asynchronous operation. The first argument to
+ * the function object represents the state of the operation, and may be used
+ * to test for cancellation. The remaining arguments are those passed to @c
+ * async_initiate after the completion token.
+ *
+ * @param io_objects_or_executors Zero or more I/O objects or I/O executors for
+ * which outstanding work must be maintained while the operation is incomplete.
+ *
+ * @par Per-Operation Cancellation
+ * By default, per-operation cancellation is disabled for composed operations
+ * that use experimental::co_composed. It must be explicitly enabled by calling
+ * the state's @c reset_cancellation_state function.
+ *
+ * @par Examples
+ * The following example illustrates manual error handling and explicit checks
+ * for cancellation. The completion handler is invoked via a @c co_yield to the
+ * state's @c complete function, which never returns.
+ *
+ * @code template <typename CompletionToken>
+ * auto async_echo(tcp::socket& socket,
+ *     CompletionToken&& token)
+ * {
+ *   return asio::async_initiate<
+ *     CompletionToken, void(std::error_code)>(
+ *       asio::experimental::co_composed(
+ *         [](auto state, tcp::socket& socket) -> void
+ *         {
+ *           state.reset_cancellation_state(
+ *             asio::enable_terminal_cancellation());
+ *
+ *           while (!state.cancelled())
+ *           {
+ *             char data[1024];
+ *             auto [e1, n1] =
+ *               co_await socket.async_read_some(
+ *                 asio::buffer(data),
+ *                 asio::as_tuple(asio::deferred));
+ *
+ *             if (e1)
+ *               co_yield state.complete(e1);
+ *
+ *             if (!!state.cancelled())
+ *               co_yield state.complete(
+ *                 make_error_code(asio::error::operation_aborted));
+ *
+ *             auto [e2, n2] =
+ *               co_await asio::async_write(socket,
+ *                 asio::buffer(data, n1),

+ *       token, std::ref(socket));
+ * } @endcode
+ *
+ * This next example shows exception-based error handling and implicit checks
+ * for cancellation. The completion handler is invoked after returning from the

+ * completion signatures passed to the @c co_composed function.

+ * @brief (Deprecated: Use the associated_executor trait.) Default invoke
+ * function for handlers.
+ *
+ * Completion handlers for asynchronous operations are invoked by the
+ * io_context associated with the corresponding object (e.g. a socket or
+ * deadline_timer). Certain guarantees are made on when the handler may be
+ * invoked, in particular that a handler can only be invoked from a thread that
+ * is currently calling @c run() on the corresponding io_context object.
+ * Handlers may subsequently be invoked through other objects (such as
+ * io_context::strand objects) that provide additional guarantees.
+ *
+ * When asynchronous operations are composed from other asynchronous
+ * operations, all intermediate handlers should be invoked using the same
+ * method as the final handler. This is required to ensure that user-defined
+ * objects are not accessed in a way that may violate the guarantees. This
+ * hooking function ensures that the invoked method used for the final handler
+ * is accessible at each intermediate step.
+ *
+ * Implement asio_handler_invoke for your own handlers to specify a custom
+ * invocation strategy.
+ *
+ * This default implementation invokes the function object like so:
+ * @code function(); @endcode
+ * If necessary, the default implementation makes a copy of the function object
+ * so that the non-const operator() can be used.
+ *
+ * @par Example
+ * @code
+ * class my_handler;
+ *
+ * template <typename Function>
+ * void asio_handler_invoke(Function function, my_handler* context)
+ * {
+ *   context->strand_.dispatch(function);

+/// Provides core I/O functionality.
+/**
+ * The io_context class provides the core I/O functionality for users of the
+ * asynchronous I/O objects, including:
+ *
+ * @li asio::ip::tcp::socket
+ * @li asio::ip::tcp::acceptor
+ * @li asio::ip::udp::socket
+ * @li asio::deadline_timer.
+ *
+ * The io_context class also includes facilities intended for developers of
+ * custom asynchronous services.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Safe, with the specific exceptions of the restart()
+ * and notify_fork() functions. Calling restart() while there are unfinished
+ * run(), run_one(), run_for(), run_until(), poll() or poll_one() calls results
+ * in undefined behaviour. The notify_fork() function should not be called
+ * while any io_context function, or any function on an I/O object that is
+ * associated with the io_context, is being called in another thread.
+ *
+ * @par Concepts:
+ * Dispatcher.
+ *
+ * @par Synchronous and asynchronous operations
+ *
+ * Synchronous operations on I/O objects implicitly run the io_context object
+ * for an individual operation. The io_context functions run(), run_one(),
+ * run_for(), run_until(), poll() or poll_one() must be called for the
+ * io_context to perform asynchronous operations on behalf of a C++ program.
+ * Notification that an asynchronous operation has completed is delivered by
+ * invocation of the associated handler. Handlers are invoked only by a thread
+ * that is currently calling any overload of run(), run_one(), run_for(),
+ * run_until(), poll() or poll_one() for the io_context.
+ *
+ * @par Effect of exceptions thrown from handlers
+ *
+ * If an exception is thrown from a handler, the exception is allowed to
+ * propagate through the throwing thread's invocation of run(), run_one(),
+ * run_for(), run_until(), poll() or poll_one(). No other threads that are
+ * calling any of these functions are affected. It is then the responsibility
+ * of the application to catch the exception.
+ *
+ * After the exception has been caught, the run(), run_one(), run_for(),
+ * run_until(), poll() or poll_one() call may be restarted @em without the need
+ * for an intervening call to restart(). This allows the thread to rejoin the
+ * io_context object's thread pool without impacting any other threads in the
+ * pool.
+ *
+ * For example:
+ *
+ * @code
+ * asio::io_context io_context;
+ * ...
+ * for (;;)
+ * {
+ *   try
+ *   {
+ *     io_context.run();
+ *     break; // run() exited normally
+ *   }
+ *   catch (my_exception& e)
+ *   {
+ *     // Deal with exception as appropriate.
+ *   }
+ * }
+ * @endcode
+ *
+ * @par Submitting arbitrary tasks to the io_context
+ *
+ * To submit functions to the io_context, use the @ref asio::dispatch,
+ * @ref asio::post or @ref asio::defer free functions.
+ *
+ * For example:
+ *
+ * @code void my_task()
+ * {
+ *   ...
+ * }
+ *
+ * ...
+ *
+ * asio::io_context io_context;
+ *
+ * // Submit a function to the io_context.
+ * asio::post(io_context, my_task);
+ *
+ * // Submit a lambda object to the io_context.
+ * asio::post(io_context,
+ *     []()
+ *     {
+ *       ...
+ *     });
+ *
+ * // Run the io_context until it runs out of work.
+ * io_context.run(); @endcode
+ *
+ * @par Stopping the io_context from running out of work
+ *
+ * Some applications may need to prevent an io_context object's run() call from
+ * returning when there is no more work to do. For example, the io_context may
+ * be being run in a background thread that is launched prior to the
+ * application's asynchronous operations. The run() call may be kept running by
+ * using the @ref make_work_guard function to create an object of type
+ * asio::executor_work_guard<io_context::executor_type>:
+ *
+ * @code asio::io_context io_context;
+ * asio::executor_work_guard<asio::io_context::executor_type>
+ *   = asio::make_work_guard(io_context);
+ * ... @endcode
+ *
+ * To effect a shutdown, the application will then need to call the io_context
+ * object's stop() member function. This will cause the io_context run() call
+ * to return as soon as possible, abandoning unfinished operations and without
+ * permitting ready handlers to be dispatched.
+ *
+ * Alternatively, if the application requires that all operations and handlers
+ * be allowed to finish normally, the work object may be explicitly reset.
+ *
+ * @code asio::io_context io_context;
+ * asio::executor_work_guard<asio::io_context::executor_type>
+ *   = asio::make_work_guard(io_context);
+ * ...
+ * work.reset(); // Allow run() to exit. @endcode

+ * The io_context::strand class provides the ability to post and dispatch
+ * handlers with the guarantee that none of those handlers will execute
+ * concurrently.
+ *
+ * @par Order of handler invocation
+ * Given:
+ *
+ * @li a strand object @c s
+ *
+ * @li an object @c a meeting completion handler requirements
+ *
+ * @li an object @c a1 which is an arbitrary copy of @c a made by the
+ * implementation
+ *
+ * @li an object @c b meeting completion handler requirements
+ *
+ * @li an object @c b1 which is an arbitrary copy of @c b made by the
+ * implementation
+ *
+ * if any of the following conditions are true:
+ *
+ * @li @c s.post(a) happens-before @c s.post(b)
+ * 
+ * @li @c s.post(a) happens-before @c s.dispatch(b), where the latter is
+ * performed outside the strand
+ * 
+ * @li @c s.dispatch(a) happens-before @c s.post(b), where the former is
+ * performed outside the strand
+ * 
+ * @li @c s.dispatch(a) happens-before @c s.dispatch(b), where both are
+ * performed outside the strand
+ *   
+ * then @c asio_handler_invoke(a1, &a1) happens-before
+ * @c asio_handler_invoke(b1, &b1).
+ * 
+ * Note that in the following case:
+ * @code async_op_1(..., s.wrap(a));
+ * async_op_2(..., s.wrap(b)); @endcode
+ * the completion of the first async operation will perform @c s.dispatch(a),
+ * and the second will perform @c s.dispatch(b), but the order in which those
+ * are performed is unspecified. That is, you cannot state whether one
+ * happens-before the other. Therefore none of the above conditions are met and
+ * no ordering guarantee is made.
+ *
+ * @note The implementation makes no guarantee that handlers posted or
+ * dispatched through different @c strand objects will be invoked concurrently.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Safe.
+ *
+ * @par Concepts:

+// If the deadline actor determines that the deadline has expired, the socket
+// is closed and any outstanding operations are consequently cancelled.

+// Connection establishment involves trying each endpoint in turn until a
+// connection is successful, or the available endpoints are exhausted. If the
+// deadline actor closes the socket, the connect actor is woken up and moves to
+// the next endpoint.

+// The deadline for receiving a complete message is 30 seconds. If a non-empty
+// message is received, it is delivered to all subscribers. If a heartbeat (a
+// message that consists of a single newline character) is received, a heartbeat
+// is enqueued for the client, provided there are no other messages waiting to

+
+[![Build Status](https://github.com/shuai132/rpc_core/workflows/build/badge.svg)](https://github.com/shuai132/rpc_core/actions?workflow=build)
+
+a tiny c++11 rpc library, supports all platforms (macOS, Linux, Windows, iOS, Android, etc.) and most microchips (
+Arduino, STM32, ESP32/ESP8266, etc.)
+
+## Introduction
+
+The complete rpc frameworks (such as `gRPC` and `brpc`) have complex functions
+and are not practical on embedded platforms.
+
+This project offers a lightweight and user-friendly rpc library that is better suited for one-to-one rpc calls.
+It supports all platforms and a wide range of microchips, including Arduino, STM32, ESP32/ESP8266, and more.
+
+Note:
+This project solely offers the protocol layer and API,
+and `does not include the implementation of the transport layer`.
+For TCP-based implementations: [asio_net](https://github.com/shuai132/asio_net)
+
+## Features
+
+* Header-Only
+* No-Schema
+* Support performance-limited platforms including microchips
+* Support any connection type (`tcp socket`, `serial port`, etc.)
+* High Performance Serialization, support most STL containers and user type
+* Serialization plugins implementations for `flatbuffers` and `nlohmann::json`
+* RAII-based `dispose` for automatic cancel request
+* Timeout and Retry API
+* Support `std::future` interface
+
+## Requirements
+
+* C++11
+* Provide your connection implementation: [connection](include/rpc_core/connection.hpp)  
+  NOTICE: complete data packets are required for data transmission, such as `websocket`.  
+  If using `tcp socket`, `serial port`, etc., message pack and unpack need to be implemented.
+  Or you can use [stream_connection](include/rpc_core/connection.hpp).
+
+## Usage
+
+```c++
+// The Receiver
+rpc->subscribe("cmd", [](const std::string& msg) -> std::string {
+    assert(msg == "hello");
+    return "world";
+});
+
+// The Sender
+rpc->cmd("cmd")
+    ->msg(std::string("hello"))
+    ->rsp([](const std::string& rsp) {
+      assert(rsp == "world");
+    })
+    ->call();
+```
+
+`msg` and `rsp` support any serializable type, see [Serialization](#Serialization).
+
+Detailed usages and unittests can be found here: [rpc_test.cpp](test/test_rpc.cpp)
+
+## Serialization
+
+High-performance and memory-saving binary serialization.
+
+For example, user data:
+
+```c++
+struct Type {
+  uint8_t id = 1;
+  uint8_t age = 18;
+  std::string name = "test";
+};
+```
+
+json: `{"id":1,"age":18,"name":"test"}`
+

+## Serialization Plugins
+
+* [flatbuffers.hpp](include/rpc_core/plugin/flatbuffers.hpp)  
+  Supports using types generated by `flatbuffers` directly as message  
+  (add the option `--gen-object-api` when using `flatc`)
+
+
+* [json_msg.hpp](include/rpc_core/plugin/json_msg.hpp)  
+  Supports using types supported by [nlohmann/json](https://github.com/nlohmann/json) directly as message  
+  (the `to_json/from_json` rules in `nlohmann/json` need to be satisfied, and use `DEFINE_JSON_CLASS`).
+
+
+* [json.hpp](include/rpc_core/plugin/json.hpp)  
+  A flexible way to use `nlohmann/json`
+
+## Links
+
+* Implementation based on asio: [asio_net](https://github.com/shuai132/asio_net)  
+  support macOS, Linux, Windows, iOS, Android, etc. and can be used on MCUs that support asio, such as ESP32.
+
+
+* Implementation suitable for ESP8266: [esp_rpc](https://github.com/shuai132/esp_rpc)
