3/21/2012 · What I am doing here is rewriting the s_dump () function for ZeroMQ 3.1 on C++11, using some stuff like casting, manipulators, auto keyword in its new skin, lambda functions, a couple of STL algorithms. All in all a piece of fun code, I’d say.
s_dump (void *socket) {int rc zmq_msg_t message rc = zmq_msg_init (&message) assert (rc == 0) puts (—–) // Process all parts of the message: do {int size = zmq_msg_recv (&message, socket, 0) assert (size >= 0) // Dump the message as text or binary: char *data = (char *) zmq_msg_data .
s_dump (sink) // Then set the identity ourselves: zmq :: socket_t identified (context, ZMQ _REQ) identified. setsockopt ( ZMQ _IDENTITY, PEER2 , 5) identified. connect ( inproc://example ) s_send (identified, ROUTER socket uses REQ’s socket identity ) s_dump .
Chapter 3 – Advanced Request-Reply Patterns # In Chapter 2 – Sockets and Patterns we worked through the basics of using ZeroMQ by developing a series of small applications, each time exploring new aspects of ZeroMQ . We’ll continue this approach in this chapter as we explore advanced patterns built on top of ZeroMQ ’s core request-reply pattern.

And you probably also need to post a minimal example of your code. (That said, the author of ZeroMQ has written a nice blog post some time ago that demonstrates that he doesn’t really understand C++ so there’s always a.
5/25/2012 · Maybe that’s a bug in gevent_ zmq , maybe that’s an issue in gevent itself.. I failed to find the real reason because the lock happened in various places in the gevent socket code. I did not spend more time on this since the bug seems to have gone away once I removed gevent altogether from the workers as we don’t use gevent there and the workers …
For the zmq ::poll or zmq::proxy , you need to cast the socket structure in void* and you mustn’t use a pointer on the socket. ZMQ poll not working. After those modification it worked. I did another post to explain why here. Here is the corrected code without my additionnal testing output :
