Hi SIMON, unfortunately I have never used libzmq (except for toy examples). I can only recommend you to add czmq (https://github.com/zeromq/czmq/) and zpoller (https://github.com/zeromq/czmq/blob/master/src/zpoller.c). As the library is based on top of libzmq, you can pass zmq sockets to zpoller_add ( https://github.com/zeromq/czmq/blob/master/src/zpoller.c#L141) or any other function accepting sockets. The advantage is that you will get MUCH easier API than zmq has.
