written to, the underlying socket; applications must retrieve the actual event
state with a subsequent retrieval of the 'ZMQ_EVENTS' option.
NOTE: The returned file descriptor is also used internally by 'zmq_send' and
'zmq_recv' functions. Given it's edge triggered nature, application must update
state of 'ZMQ_EVENTS' after each invocation of 'zmq_send' or 'zmq_recv'.
To be more explicit: after calling 'zmq_send' socket may become readable (and
vice versa) without triggering read event on file descriptor.
