[zeromq-dev] Examples and returned errors

The setsockopt call isn't failing.

Try this code:

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

Some of the simpler Guide examples don't check the return code. It's
something I'll fix for the next release.
