[zeromq-dev] basic question - integrating zmq with a windows message pump

[David.Briant at ubs.com]

thx for the heads up... I'll give that a miss for the moment as I'm
developing in python and haven't learnt how to use pyrex yet...

In the trunk, there's no such option.

However, you can try sustrik/zeromq2, an experimental branch that 
exposes ZMQ_FD and ZMQ_EVENTS socket option.

getsockopt(ZMQ_FD) returns the file descriptor associated with the 0MQ 
socket. You can use WSAAsyncSelect on it, specifying FD_READ as lEvent.

Once the event is triggered, it means something has happened with the 
socket. At that point, do getsockopt (ZMQ_EVENTS) that'll let you know 
whether socket is ready for reasing writing or both.

Martin
