- zmq_atomic_counter_destroy(3)
- =============================
- NAME
- ----
- zmq_atomic_counter_destroy - destroy an atomic counter
- SYNOPSIS
- --------
- *void zmq_atomic_counter_destroy (void **counter_p);*
- DESCRIPTION
- -----------
- 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.
- RETURN VALUE
- ------------
- The _zmq_atomic_counter_destroy()_ function has no return value.
- 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;
