Dear Nils, > I would like to connect my ZeroMQ application with a > non-zeromq one via a ZMQ_STREAM socket type.
I think, in my way of looking at it, that you wouldn't be connecting to a non-zeromq application. Instead, you'd be writing your own implementation of the zeromq protocol in order to communicate with the zeromq library over (part of) the zeromq protocol. Why would you need to re-write zeromq? Certainly, it will be educational... But I'm not sure I could recommend this scenario in any conceivable production setting. > Is it possible to test if the socket is writable and a send > would not block via the usage of poll (with POLLOUT)? I've really only used REQ / REP with DEALER / BROKER myself. I can say that in my configuration ZeroMQ will definitely block on certain calls. Most notably, all data must be completely sent before the remote side will begin reading any result. I think this is partly fundamental to how "queuing" works in ZeroMQ. Some level of data chunk will always be fully completed and secured (usually at message level) before the remote end can begin to dequeue that chunk. Someone please correct me if I'm wrong here. I have not read the code! Good luck with your configuration, Robert E. _______________________________________________ zeromq-dev mailing list [email protected] https://lists.zeromq.org/mailman/listinfo/zeromq-dev
