SYNOPSIS
void zmq_atomic_counter_set (void *counter, int value);
DESCRIPTION
The zmq_atomic_counter_set function sets the counter to a new value, in a threadsafe fashion. The largest value that is guaranteed to work across all platforms is 2^31-1. This function uses platform specific atomic operations.
RETURN VALUE
The zmq_atomic_counter_set() 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;
