zmq_init(3)
===========
NAME
----
zmq_init - initialises 0MQ context
SYNOPSIS
--------
'void *zmq_init (int app_threads, int io_threads, int flags);'
DESCRIPTION
-----------
Initialises 0MQ context. 'app_threads' specifies maximal number of application
threads that can own open sockets at the same time. At least one application
thread should be defined. 'io_threads' specifies the size of thread pool to
handle I/O operations. The value shouldn't be negative. Zero can be used in
case only in-process messaging is going to be used, i.e. there will be no I/O
traffic.
The 'flags' argument is a combination of the flags defined below:
*ZMQ_POLL*::
flag specifying that the sockets within this context should be pollable
(see linkzmq:zmq_poll[3]). Pollable sockets may add a little latency to the
message transfer when compared to non-pollable sockets.
RETURN VALUE
------------
Function returns context handle is successful. Otherwise it returns NULL and
sets errno to one of the values below.
ERRORS
------
*EINVAL*::
there's less than one application thread allocated, or number of I/O
threads is negative.
EXAMPLE
-------
----
void *ctx = zmq_init (1, 1, ZMQ_POLL);
assert (ctx);
