Hi,
Here's the code in the sender (C++):
zmq::message_t reply (3);
memcpy ((void *) reply.data (), "OK", 2);
socket.send (reply);
It's an almost literal copy from the guide:
// Send reply back to client
zmq::message_t reply (6);
memcpy ((void *) reply.data (), "World", 5);
socket.send (reply);
So I guess I should have reported an error in the guide.
Thanks for the prompt replies. I've reverted my patch.
Han Holl
