[zeromq-dev] REQ-REP Timeouts in PyZMQ

[Benjamin]

Hi,

here is an example with polling:
https://github.com/imatix/zguide/blob/master/examples/Python/asyncsrv.py
So the client raises an exception after a pre-defined time-period (1
second e.g.)

Check out the socket options here
http://api.zeromq.org/4-1:zmq-setsockopt   (ZMQ_RCVTIMEO and
ZMQ_SNDTIMEO)
