zmq_init(3) Manual Page

void *zmq_init (int io_threads);

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.

A ØMQ context is thread safe and may be shared among as many application threads as necessary, without any additional locking required on the part of the caller.

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.
