- (including the terminating null wide-character code) to the end of the
- wide-character string pointed to by
- .IR ws1 .
- The initial wide-character code of
- .IR ws2
- shall overwrite the null wide-character code at the end of
- .IR ws1 .
- If copying takes place between objects that overlap, the behavior is
