zmq_atomic_counter_destroy - destroy an atomic counter

void zmq_atomic_counter_destroy (void **counter_p);

The zmq_atomic_counter_destroy function destroys an atomic counter and nullifies its reference. Pass the address of an atomic counter (void **) rather than the counter itself. You must destroy all counters that you create, to avoid memory leakage. This function uses platform specific atomic operations.

The zmq_atomic_counter_destroy() function has no return value.

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;
