Re: [zeromq-dev] polling for messages
Hi Alex, That'll be fine - the fd events are edge-triggered and would work with any reactor implementation. Just remember to read until completion as the notification can be for more than one message (zmq protocol is framed) as well. Failure to do so will result in further notifications not being triggered. - Lourens On Monday, March 26, 2012, Pieter Hintjens wrote: > Yes, it should work fine. > > On Mar 26, 2012 11:44 AM, "Alex Zeffertt" wrote: >> >> Hi list, >> >> I'm considering using czmq in my single threaded application. >> However, the application is already using an event driven framework in >> which a file descriptor has to be registered along with a callback >> that is invoked when it becomes readable. >> >> My question is: can I use the file descriptor returned by >> zsockopt_fd() in this way, or would this break things when I issue >> zframe_recv_nowait()? >> >> Thanks in advance, >> >> Alex >> ___ >> zeromq-dev mailing list >> zeromq-dev@lists.zeromq.org >> http://lists.zeromq.org/mailman/listinfo/zeromq-dev >> > ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev

Yes, it should work fine.

[zeromq-dev] polling for messages
Hi list, I'm considering using czmq in my single threaded application. However, the application is already using an event driven framework in which a file descriptor has to be registered along with a callback that is invoked when it becomes readable. My question is: can I use the file descriptor returned by zsockopt_fd() in this way, or would this break things when I issue zframe_recv_nowait()?
