va_end - cppreference.com
void va_end( va_list ap );
The va_end macro performs cleanup for an ap object initialized by a call to va_start or va_copy. va_end may modify ap so that it is no longer usable.
If there is no corresponding call to va_start or va_copy, or if va_end is not called before a function that calls va_start or va_copy returns, the behavior is undefined.
[edit] Parameters ap - an instance of the va_list type to clean up [edit] Expanded value
(none)
