NAME

zmq_atomic_counter_dec - decrement an atomic counter  

SYNOPSIS

int zmq_atomic_counter_dec (void *counter);  

DESCRIPTION

The zmq_atomic_counter_dec function decrements an atomic counter in a threadsafe fashion. This function uses platform specific atomic operations.  

RETURN VALUE

The zmq_atomic_counter_dec() function returns 1 if the counter is greater than zero after decrementing, or zero if the counter reached zero.  

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;
