* 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_atomic_counter_new - create a new atomic counter
|
|
|
|
|
|
== SYNOPSIS
|
|
*void *zmq_atomic_counter_new (void);*
|
|
|
|
|
|
== DESCRIPTION
|
|
The _zmq_atomic_counter_new_ function creates a new atomic counter. You
|
|
can use this in multithreaded applications to do, for example, reference
|
|
counting of shared objects. The atomic counter is at least 32 bits large.
|
|
This function uses platform specific atomic operations.
|
|
|
|
|
|
== RETURN VALUE
|
|
The _zmq_atomic_counter_new()_ function returns the new atomic counter
|
|
if successful. Otherwise it returns NULL.
|
|
|
|
|
|
== EXAMPLE
|
|
.Test code for atomic counters
