[zeromq-dev] Router-Dealer Example not working in C on 4.0.4 ZMQ release

[Pieter Hintjens]

There are no known issues, so it's presumably something in your
example. The best way to debug such uncertainties is to write a single
program that does all the work in one thread, e.g.

#include <czmq.h>

int main (void)
{
    zsock_t *router = zsock_new_router ("tcp://127.0.0.1:9990");
    zsock_t *dealer = zsock_new_dealer ("tcp://127.0.0.1:9990");

    zstr_send (dealer, "Hello World");
    zmsg_t *msg = zmsg_recv (router);
    zmsg_print (msg);
    zmsg_send (&msg, router);
    msg = zmsg_recv (dealer);
    zmsg_print (msg);

    zmsg_destroy (&msg);
    zsock_destroy (&router);
    zsock_destroy (&dealer);
    return 0;
}

(using CZMQ master with latest API calls)
