ZMQ_ATOMIC_COUNTER_V(3) 0MQ Manual ZMQ_ATOMIC_COUNTER_V(3)
NAME
zmq_atomic_counter_value - return value of atomic counter
SYNOPSIS
int zmq_atomic_counter_value (void *counter);
DESCRIPTION
The zmq_atomic_counter_value function returns the value of an atomic
counter created by zmq_atomic_counter_new(). This function uses
platform specific atomic operations.
RETURN VALUE
The zmq_atomic_counter_value() function returns the value of the atomic
counter. If counter does not point to an atomic counter created by
zmq_atomic_counter_new(), the behaviour is undefined.
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;
