I was trying to get zmq_poll working but for some reason my app crashes event when I init the ctx with the ZMQ_POLL flag.
It'll crash inside zmq_poll at : pollfds [npollfds].fd = app_thread->get_signaler ()->get_fd (); for some reasons app_thread->get_signaler () is NULL. Anyhow, I just thought I drop a line wrt the zmq_recv documentation. Looking at the *ZMQ_NOBLOCK *section it states Specifies that the operation should be performed in non-blocking mode. If there are no messages available to be dequeued from the underlying /message queue/ associated with /socket/, the /zmq_recv()/ function shall fail with /errno/ set to EAGAIN. So I was expecting the function to return -1, as stated a few lines further down * RETURN VALUE* The /zmq_recv()/ function shall return zero if successful. Otherwise it shall return -1 and set /errno/ to one of the values defined below. However if no msg is available it'll return 0, else 1. ( on Linux ) Smehow there seems to be a disconnect between those two. Varol :) _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
