                    | 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.
[edit] Parameters
