Hi all,
The current trunk now fully supports multi-part messages.
To send a multi-part messages, use ZMQ_SNDMORE flag when sending all but
the last part of the message:
zmq::message_t part1;
zmq::message_t part2;
s.send (part1, ZMQ_SNDMORE);
s.send (part2);
On the receiver side recv the messages as normal. To find out whether
there are more message parts to be received, use ZMQ_RCVMORE socket option:
while (true) {
s.recv (&msg);
uint64_t more;
size_t sz = sizeof (more);
s.getsockopt (ZMQ_RCVMORE, &more, &sz);
if (!more)
break;
}
Not to break the language bindings that define obsoleted ZMQ_MORE
constant, the constant is still present and synonymous with ZMQ_SNDMORE.
However, it will be removed for 2.0.7 release and thus the bindings
should be modified to expose ZMQ_SNDMORE and ZMQ_RCVMORE instead of
ZMQ_MORE.
