SYNOPSIS

void *zmq_init (int io_threads);

DESCRIPTION

The zmq_init() function initialises a ØMQ context.

The io_threads argument specifies the size of the ØMQ 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.
