# czmq(7)

Overview of The high-level C binding for 0MQ

## NAME

czmq - Overview of The high-level C binding for 0MQ

## SYNOPSIS

Project czmq aims to ... (short marketing pitch)

It delivers several programs with their respective man pages: zmakecert.1 and public classes in a shared library: zactor.3 zarmour.3 zcert.3 zcertstore.3 zchunk.3 zclock.3 zconfig.3 zdigest.3 zdir.3 zdir\_patch.3 zfile.3 zframe.3 zhash.3 zhashx.3 ziflist.3 zlist.3 zlistx.3 zloop.3 zmsg.3 zpoller.3 zproc.3 zsock.3 zstr.3 ztimerset.3 ztrie.3 zuuid.3 zauth.3 zbeacon.3 zgossip.3 zmonitor.3 zproxy.3 zrex.3 zsys.3

Generally you can compile and link against it like this:

```
#include <czmq.h>
cc ['flags'] 'files' -lczmq ['libraries']
```

## DESCRIPTION

This is a skeleton document created by zproject, which will not be regenerated automatically (by Makefiles nor project.xml re-parsing). You should add hand-written text here to detail whatever applies to Linux standard manpage Section 7 (note that other OSes may follow a different standard with similar concepts, and extend the recipes to package this document into a different section number):

```
7 Overview, conventions, and miscellaneous :
    Overviews or descriptions of various topics, conventions
    and protocols, character set standards, the standard
    filesystem layout, and miscellaneous other things.
```

### Classes

Something for developers to consider. Note there are separate man pages generated for public classes during build with contents taken from source code comments.

## AUTHORS

The czmq manual was written by the authors in the AUTHORS file.
