Yes, you need to use zmq_poll. Take a look at the Ruby FFI bindings (ffi-rzmq gem) and look at the examples. There is at least one showing how to use the poller. And don't worry about FFI being slow. It has gotten a lot of optimization attention from both the JRuby and Rubinius projects. The maintainer of the 'ffi' gem for JRuby also maintains it for MRI. In my benchmarking, FFI adds about 1 microsecond of overhead on each call. cr _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
