Thanks for the reply. I took a look, and my understanding is that the CZMQ zproxy class waits for messages from both a backend and a pipe (which is a PAIR socket to expose the API) and updates a local variable 'stopped' which ends the loop when the pipe receives the 'STOP' command.
And it refers to that as a 'steerable proxy'. Then, I found that there is a class in libzmq called zmq_proxy_steerable ( http://api.zeromq.org/4-1:zmq-proxy-steerable), which seems to offer exactly what I was asking about. Why isn't CZMQ zproxy using zmq_proxy_steerable? For C++ programming, cppzmq doesn't wrap either of those classes. Niether does zmqpp. So, I'm wondering, what pattern do other people who are using ZeroMQ in C++ currently follow in this case to control their proxy loops? I suppose one solution is the one mentioned in the other thread, namely, wrapping CZMQ in your C++ application. Any suggestions?
