If linger is specified, LINGER sockopt will be set prior to closing. Note: closing a zmq Socket may not close the underlying sockets if there are undelivered messages. Only after all messages are delivered or discarded by reaching the socket's LINGER timeout (default: forever) will the underlying sockets be closed. This can be called to close the socket by hand.

This queues the message to be sent by the IO thread at a later time. With flags=NOBLOCK, this raises :class:`ZMQError` if the queue is full; otherwise, this waits until space is available. See :class:`Poller` for more general non-blocking I/O. Parameters ---------- data : bytes, Frame, memoryview The content of the message. This can be any object that provides the Python buffer API (i.e. `memoryview(data)` can be called). flags : int 0, NOBLOCK, SNDMORE, or NOBLOCK|SNDMORE. copy : bool Should the message be sent in a copying or non-copying manner. track : bool Should the message be tracked for notification that ZMQ has finished with it? (ignored if copy=True) routing_id : int For use with SERVER sockets group : str For use with RADIO sockets Returns ------- None : if `copy` or not track None if message was sent, raises an exception otherwise. MessageTracker : if track and not copy a MessageTracker object, whose `pending` property will be True until the send is completed. Raises ------ TypeError If a unicode object is passed ValueError If `track=True`, but an untracked Frame is passed. ZMQError If the send does not succeed for any reason (including if NOBLOCK is set and the outgoing queue is full). .. versionchanged:: 17.0 DRAFT support for routing_id and group arguments.

The zmq.SNDMORE flag is added to all msg parts before the last. Parameters ---------- msg_parts : iterable A sequence of objects to send as a multipart message. Each element can be any sendable object (Frame, bytes, buffer-providers) flags : int, optional Any valid flags for :func:`Socket.send`. SNDMORE is added automatically for frames before the last. copy : bool, optional Should the frame(s) be sent in a copying or non-copying manner. If copy=False, frames smaller than self.copy_threshold bytes will be copied anyway. track : bool, optional Should the frame(s) be tracked for notification that ZMQ has finished with it (ignored if copy=True).
