You can call zmq_msg_get with ZMQ_SRCFD, however this option is deprecated
and I don't recommend it.

Instead you can call the zmq_msg_gets to get metadata about the socket,
right now only "Peer-Address" is supported but it is pretty easy to add
more properties.

If you want to add more this is the place
