va_end
Defined in header <stdarg.h> |
||
|---|---|---|
|
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)
