[zeromq-dev] zmq_poll not working on Windows

[Marko.Dieckmann at gmx.de]

Hi Mikko,

 Thanks for the quick response!
 That was it indeed. It's working now.

 It's a bit confusing, though, because the struct has a void* in it. So I thought he wants the pointer. ;)
 I'll look at the samples more closely next time.

 Cheers,
 Marko

Try: zmq_pollitem_t pi[] = { *m_pInprocSocket, 0, ZMQ_POLLIN, 0 }; thanks, mikko _______________________________________________ zeromq-dev mailing list zeromq-dev at lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev
