I apologize for my little knowledge.
What do you mean when you say "you can debug that"?

Ok, setsockopt return 0. So we know it should be ok.
But:

   printf("errno = %d\n", zmq_errno());
   int rc = zmq_setsockopt (publisher, ZMQ_HWM, &hwm, sizeof (hwm));
   printf("errno = %d\n", zmq_errno());

returns:

errno = 0
errno = 22

We know that before setsockopt errno = 0, and right after is 22.
What part of the code should I debug? And how?
