ZMQ_ATOMIC_COUNTER_D(3) 0MQ Manual ZMQ_ATOMIC_COUNTER_D(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;
