Hi everyone, New Zeromq user here. Please bear with me if the answer to this question is blindingly obvious.
I'm trying to use zeromq with select/epoll so that I can have a single thread multiplex between different inputs. After reading the documentation on ZMQ_FD, I found that it works for ZMQ_REP sockets but not for ZMQ_REQ sockets. I've basically modified the hello world server and client (the waitForIt function is the same in both files): Server code: http://pastebin.com/eBNaSVYC Client code: http://pastebin.com/ivt1xfa0 What happens is that the server (ZMQ_REP) gets the request and sends a reply, but the client (ZMQ_REQ) never gets signaled for the reply, so the select times out. If we change the client to not use select, or use the default client, everything works fine. Working client code: http://pastebin.com/sg5QyZC2 Reading through the list, I also tried changing the client from ZMQ_REQ to ZMQ_DEALER, but that didn't work either. Does anyone know why the file descriptor for ZMQ_REP gets triggered but the file descriptor for ZMQ_REQ does not? Is this a bug, or am I doing something wrong? I'm running ZeroMQ 2.1.10 on Linux with GCC 4.4. Thanks in advance, Yi _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
