zmq_init - initialise 0MQ context
void *zmq_init (int app_threads, int io_threads, int flags);
The zmq_init() function initialises a 0MQ context with app_threads
application threads and io_threads I/O threads.
The app_threads argument specifies the maximum number of application
threads that will be using 0MQ sockets in this context. As a guide, set
this to the number of threads in your application.
The io_threads argument specifies the size of the 0MQ thread pool to
handle I/O operations. If your application is using inproc messaging
exclusively you may set this to zero, otherwise set it to at least one.
The flags argument is a combination of the flags defined below:
Specifies that sockets within this context should support
multiplexing using zmq_poll(). Enabling this functionality may add
a small amount of latency to message transfers compared to leaving
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.
The number of app_threads requested is less than one, or the number
of io_threads requested is negative.
