One little thing that tripped me up. If you're using PGM, sending though a PUB and listening for incoming traffic on a SUB, you might think you only need to monitor the FD on the SUB socket. In fact any NAK from a client gets sent to the PUB socket, so you need to monitor it's FD for incoming traffic too. Using either to trigger calling zmq_poll() on the SUB socket will get NAK responses sent properly. If you don't monitor the PUB socket FD, only call zmq_recv() or zmq_poll() on an event, and don't have any traffic to zmq_send(), PGM NAKs won't get processed. -- Jim Hague - jim.ha...@acm.org Never trust a computer you can't lift. _______________________________________________ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev
