[zeromq-dev] Adding new zmq_getsockopt() to retrieve number of subscriptions from XPUB socket

[Francesco]

As far as I know (by reading docs) zmq_socket_monitor() and also the
newer zmq_socket_monitor_versioned() do not allow to monitor
subscriptions, just endpoints... what am I missing?

Thanks,
Francesco
