NAME

       zmq_init - initialise 0MQ context

SYNOPSIS

       void *zmq_init (int app_threads, int io_threads, int flags);

DESCRIPTION

       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:

       ZMQ_POLL
           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
           it disabled.

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
           The number of app_threads requested is less than one, or the number
           of io_threads requested is negative.
