I run the code (http://zguide.zeromq.org/cpp:rtpapa) on Window (ZeroMQ
version 3.2.0) and get a error (errno = EFSM and comment "If we are in
middle of sending a reply, we cannot receive next request."). Help me fix

// http://zguide.zeromq.org/cpp:rtpapa
// Custom routing Router to Papa (ROUTER to REP)
// Olivier Chamoux <olivier.chamoux at fr.thalesgroup.com>

#include "zhelpers.hpp"

// We will do this all in one thread to emphasize the sequence
// of events…
int main () {
zmq::context_t context(1);

zmq::socket_t client (context, ZMQ_ROUTER);


zmq::socket_t worker (context, ZMQ_REP);
worker.setsockopt(ZMQ_IDENTITY, "A", 1);


*// Wait for sockets to stabilize*
sleep (1000);

*// Send papa address, address stack, empty part, and request*
s_sendmore (client, "A");
s_sendmore (client, "address 3");
s_sendmore (client, "address 2");
s_sendmore (client, "address 1");
s_sendmore (client, "");
s_send (client, "This is the workload");

*// Worker should get just the workload*
s_dump (worker);

*// We don't play with envelopes in the worker*
s_send (worker, "This is the reply");

*// Now dump what we got off the ROUTER socket…*
s_dump (client);

*return* 0;
