NAME

|
----
|
|
zmq_init - initialise 0MQ context
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
*void *zmq_init (int 'io_threads');*
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
The _zmq_init()_ function initialises a 0MQ 'context'.
|
|
|
|
The 'io_threads' argument specifies the size of the 0MQ thread pool to handle
|
|
I/O operations. If your application is using only the 'inproc' transport for
|
|
messaging you may set this to zero, otherwise set it to at least one.
|
|
|
|
|
|
RETURN VALUE
|
|
------------
|
|
The _zmq_init()_ function shall return an opaque handle to the initialised
|
|
'context' if successful. Otherwise it shall return NULL and set 'errno' to one
|
|
of the values defined below.
|
|
|
|
|
|
ERRORS
|
|
------
|
|
*EINVAL*::
|
|
An invalid number of 'io_threads' was requested.
