EXAMPLE
-------
.Test code for atomic counters
----
void *counter = zmq_atomic_counter_new ();
assert (zmq_atomic_counter_value (counter) == 0);
assert (zmq_atomic_counter_inc (counter) == 0);
assert (zmq_atomic_counter_inc (counter) == 1);
assert (zmq_atomic_counter_inc (counter) == 2);
assert (zmq_atomic_counter_value (counter) == 3);
assert (zmq_atomic_counter_dec (counter) == 1);
assert (zmq_atomic_counter_dec (counter) == 1);
assert (zmq_atomic_counter_dec (counter) == 0);
zmq_atomic_counter_set (counter, 2);
assert (zmq_atomic_counter_dec (counter) == 1);
assert (zmq_atomic_counter_dec (counter) == 0);
zmq_atomic_counter_destroy (&counter);
return 0;
