Defined in header <stdarg.h>
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.

Parameters

ap

-

an instance of the va_list type to clean up

Expanded value

(none)
