ZMQ_INIT(3)                       0MQ Manual                       ZMQ_INIT(3)



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.

       Thread safety. A 0MQ 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.

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.
