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.

       This function is deprecated by zmq_ctx_new(3).

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.
