Examples
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;
