Question

Is it possible to use zmq.Poller to also poll for data availability on stdin? If not, what would be the most efficient wait to poll, at the some time (ideally), for data availability on zeromq sockets & stdin?

Answer 1

yes, zmq pollers do support native FDs, including stdin, etc., so you just need to check sys.stdin.fileno():

poller = zmq.Poller()
poller.register(sys.stdin, zmq.POLLIN)
poller.register(mysocket, zmq.POLLIN)
evts = dict(poller.poll(1000))
stdin_ready = evts.get(sys.stdin.fileno(), False)
socket_ready = evts.get(mysocket, False)
