NAME

6       zmq_atomic_counter_destroy - destroy an atomic counter
7

SYNOPSIS

9       void zmq_atomic_counter_destroy (void **counter_p);
10

DESCRIPTION

12       The zmq_atomic_counter_destroy function destroys an atomic counter and
13       nullifies its reference. Pass the address of an atomic counter (void
14       **) rather than the counter itself. You must destroy all counters that
15       you create, to avoid memory leakage. This function uses platform
16       specific atomic operations.
17

RETURN VALUE

19       The zmq_atomic_counter_destroy() function has no return value.
20

EXAMPLE

22       Test code for atomic counters.
23
24           void *counter = zmq_atomic_counter_new ();
25           assert (zmq_atomic_counter_value (counter) == 0);
26           assert (zmq_atomic_counter_inc (counter) == 0);
27           assert (zmq_atomic_counter_inc (counter) == 1);
28           assert (zmq_atomic_counter_inc (counter) == 2);
29           assert (zmq_atomic_counter_value (counter) == 3);
30           assert (zmq_atomic_counter_dec (counter) == 1);
31           assert (zmq_atomic_counter_dec (counter) == 1);
32           assert (zmq_atomic_counter_dec (counter) == 0);
33           zmq_atomic_counter_set (counter, 2);
34           assert (zmq_atomic_counter_dec (counter) == 1);
35           assert (zmq_atomic_counter_dec (counter) == 0);
36           zmq_atomic_counter_destroy (&counter);
37           return 0;
