example for zmq_poll usage with ZeroMQ::Raw

Hi Daisuke, thank you for writing the ZeroMQ Perl library, I appreciate your work :-) Would you mind writing a quick example for how to use zmq_poll and ZeroMQ::Raw? In the documentation section "ASYNCHRONOUS I/O WITH ZEROMQ" you have described how to setup the zmq_poll hash with callbacks, but not the parameters passed to the callbacks or how to extract messages in the callbacks. I've tried reading thru the sourcecode in ZeroMQ- 0.21/lib/ZeroMQ/Poller.pm, but my Perl isn't good enough to deciper how you're using zmq_poll: 18 sub poll { ... 25 zmq_poll($self->_raw_poll_items, $timeout); 26 } Thanks, Sonia.

Please use ZMQ::LibZMQ2 ( or ZMQ::LibZMQ3 ). ZeroMQ was a good attempt, but differences between versions of libzmq makes it extremely hard for bindings to keep a sane API. for an example, see https://github.com/lestrrat/p5-ZMQ/blob/master/ZMQ- LibZMQ2/t/006_anyevent.t#L18-29 but if it's in Perl, I'd suggest using AnyEvent (example in the same file) p.s. LibZMQ3 is only on github at the moment

Thanks Daisuke, I'll check out versions 2 & 3. I was more interested in examples, but I worked it out anyway: sub master_callback { my $msg = zmq_msg_data(zmq_recv($master_ch)); Perhaps you should include an example like this in the doco? Sonia. Show quoted text
