* 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

= zmq_msg_init_size(3)

|
|
== NAME
|
|
zmq_msg_init_size - initialise 0MQ message of a specified size
|
|
|
|
|
|
== SYNOPSIS
|
|
*int zmq_msg_init_size (zmq_msg_t '*msg', size_t 'size');*
|
|
|
|
|
|
== DESCRIPTION
|
|
The _zmq_msg_init_size()_ function shall allocate any resources required to
|
|
store a message 'size' bytes long and initialise the message object referenced
|
|
by 'msg' to represent the newly allocated message.
|
|
|
|
The implementation shall choose whether to store message content on the stack
|
|
(small messages) or on the heap (large messages). For performance reasons
|
|
_zmq_msg_init_size()_ shall not clear the message data.
|
|
|
|
CAUTION: Never access 'zmq_msg_t' members directly, instead always use the
|
|
_zmq_msg_ family of functions.
|
|
|
|
CAUTION: The functions _zmq_msg_init()_, _zmq_msg_init_data()_,
|
|
_zmq_msg_init_size()_ and _zmq_msg_init_buffer()_ are mutually exclusive.
|
|
Never initialise the same 'zmq_msg_t' twice.
|
|
|
|
|
|
== RETURN VALUE
|
|
The _zmq_msg_init_size()_ function shall return zero if successful. Otherwise
|
|
it shall return `-1` and set 'errno' to one of the values defined below.
|
|
|
|
|
|
== ERRORS
|
|
*ENOMEM*::
|
|
Insufficient storage space is available.
