    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)
