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.
|
||
|
|
|
||
|
