- zmq_atomic_counter_set(3)
- =========================
- NAME
- ----
- zmq_atomic_counter_set - set atomic counter to new value
- 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;
