<p>Returns a series of operating system-specific exception codes. </p>
<p>The precise interpretation of these codes is specific to the snapshot operating system. These codes may provide a duplicate of information available elsewhere, they may extend information available elsewhere, or they may not be present at all. In this case, an empty vector will be returned.</p>
<p>For Mac OS X, this will be a vector containing the original exception type and the values of <code>code[0]</code> and <code>code[1]</code> as received by a Mach exception handler.</p>
<p>For Windows, these are additional arguments (if any) as provided to <code>RaiseException()</code>. See the documentation for <code><aclass="el"href="structcrashpad_1_1ExceptionInformation.html"title="Structure read out of the client process by the crash handler when an exception occurs. ">ExceptionInformation</a></code> in <code>EXCEPTION_RECORD</code>. </p>
<p>Returns a <aclass="el"href="structcrashpad_1_1CPUContext.html"title="A context structure capable of carrying the context of any supported CPU architecture. ">CPUContext</a> object corresponding to the exception thread’s CPU context at the time of the exception. </p>
<p>The caller does not take ownership of this object, it is scoped to the lifetime of the <aclass="el"href="classcrashpad_1_1ThreadSnapshot.html"title="An abstract interface to a snapshot representing a thread (lightweight process) present in a snapshot...">ThreadSnapshot</a> object that it was obtained from. </p>
<p>For Mac OS X, this will be an <aclass="el"href="non__mac_2mach_2mach_8h.html#EXC_x">EXC_*</a> exception type, such as <code>EXC_BAD_ACCESS</code>. <code>EXC_CRASH</code> will not appear here for exceptions processed as <code>EXC_CRASH</code> when generated from another preceding exception: the original exception code will appear instead. The exception type as it was received will appear at index 0 of <aclass="el"href="classcrashpad_1_1internal_1_1ExceptionSnapshotMac.html#a3179b8de3f86e150cf6d1d3078dd8109"title="Returns a series of operating system-specific exception codes. ">Codes()</a>.</p>
<p>Returns the address that triggered the exception. </p>
<p>This may be the address that caused a fault on data access, or it may be the instruction pointer that contained an offending instruction. For exceptions where this value cannot be determined, it will be <code>0</code>.</p>
<p>For Mac OS X, this will be the value of the exception code at index 1 as received by a Mach exception handler. </p>
<p>Returns the second-level exception code identifying the exception. </p>
<p>This is an operating system-specific value.</p>
<p>For Mac OS X, this will be the value of the exception code at index 0 as received by a Mach exception handler, except:</p><ul>
<li>For <code>EXC_CRASH</code> exceptions generated from another preceding exception, the original exception code will appear here, not the code as received by the Mach exception handler.</li>
<li>For <code>EXC_RESOURCE</code> and <code>EXC_GUARD</code> exceptions, the high 32 bits of the exception code at index 0 will appear here.</li>
<p>In all cases on Mac OS X, the full exception code at index 0 as it was received will appear at index 1 of <aclass="el"href="classcrashpad_1_1internal_1_1ExceptionSnapshotMac.html#a3179b8de3f86e150cf6d1d3078dd8109"title="Returns a series of operating system-specific exception codes. ">Codes()</a>.</p>
<p>On Windows, this will either be <code>0</code> if the exception is continuable, or <code>EXCEPTION_NONCONTINUABLE</code> to indicate a noncontinuable exception. </p>
<p>Returns a vector of additional memory blocks that should be included in a minidump. </p>
<dlclass="section return"><dt>Returns</dt><dd>A vector of <aclass="el"href="classcrashpad_1_1MemorySnapshot.html"title="An abstract interface to a snapshot representing a region of memory present in a snapshot process...">MemorySnapshot</a> objects that will be included in the crash dump.
