va_end - cppreference.com (original) (raw)
| | | | | ---------------------------- | | | | 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
