* migrate from the old, unmaintained "asciidoc-py" tool to the new "asciidoctor" generator * migrate from asciidoc-py syntax to the modern Asciidoc syntax (especially page titles and section titles) * remove the need of "xmlto" utility to create the manpage output; use asciidoctor for that * add HTML output support to the doc/Makefile by using asciidoctor * change API documentation files extension from .txt to .adoc to make it more explicit that they are Asciidoc-encoded (as a bonus several IDE plugins will autodetect the .adoc format as Asciidoc) * remove asciidoc.conf: asciidoctor does not support that; this also required replacing the macro linkzmq into all documentation pages * add a new Github action CI do deploy to Github Pages the static HTMLs produced by Asciidoctors * removed references to the "xmlto" and "a2x" tools from the build and packaging systems: Asciidoctor can convert the documentation directly to e.g. pdf (via extended converters) and anyway there was no code/target for using "xmlto" and "a2x" tools anyway

== NAME
|
|
zmq_msg_close - release 0MQ message
|
|
|
|
|
|
== SYNOPSIS
|
|
*int zmq_msg_close (zmq_msg_t '*msg');*
|
|
|
|
|
|
== DESCRIPTION
|
|
The _zmq_msg_close()_ function shall inform the 0MQ infrastructure that any
|
|
resources associated with the message object referenced by 'msg' are no longer
|
|
required and may be released. Actual release of resources associated with the
|
|
message object shall be postponed by 0MQ until all users of the message or
|
|
underlying data buffer have indicated it is no longer required.
|
|
|
|
Applications should ensure that _zmq_msg_close()_ is called once a message is
|
|
no longer required, otherwise memory leaks may occur. Note that this is NOT
|
|
necessary after a successful _zmq_msg_send()_.
|
|
|
|
CAUTION: Never access 'zmq_msg_t' members directly, instead always use the
|
|
_zmq_msg_ family of functions.
|
|
|
|
|
|
== RETURN VALUE
|
|
The _zmq_msg_close()_ function shall return zero if successful. Otherwise
|
|
it shall return `-1` and set 'errno' to one of the values defined below.
|
|
|
|
|
|
== ERRORS
|
|
*EFAULT*::
|
|
Invalid message.
