[zeromq-dev] question about recv_identity in the libzmq code

[Laurent Alebarde]

Hi Devs,

In socket_base.cpp, there is this code:

             //  If required, send the identity of the local socket to 
the peer.
             if (peer.options.recv_identity) {

                 msg_t id;
                 rc = id.init_size (options.identity_size);
                 errno_assert (rc == 0);
                 memcpy (id.data (), options.identity, 
options.identity_size);
                 id.set_flags (msg_t::identity);
                 bool written = new_pipes [0]->write (&id);
                 zmq_assert (written);
                 new_pipes [0]->flush ();
             }

.recv_identity is true for a ROUTER socket. Could one please explain me 
in which case / context this is usefull for ?
