There is no way for zeromq to immediately return an error. Zeromq is a message queueing library where each socket may have many peers. It allows the network connections to go up and down without always notifying the programmer that the network changed state.

If you need this information, I recommend looking at the documentation for zmq_socket_monitor.


Alternately, instead of using PUSH/PULL take a look at chapters 4 and 5 in the guide for patterns using DEALER/ROUTER sockets that might be appropriate. Many of those patterns provide for bidirectional communication so you can add your own heartbeats, timeouts and other mechanisms for detecting network failure.
