wchar_t *wcscat(wchar_t *restrict ws1, const wchar_t *restrict
The wcscat() function shall append a copy of the wide-character string pointed to by ws2 (including the terminating null wide-character code) to the end of the wide-character string pointed to by ws1. The initial wide-character code of ws2 shall overwrite the null wide-character code at the end of ws1. If copying takes place between objects that overlap, the behavior is undefined.
The wcscat() function shall return ws1; no return value is reserved to indicate an error.
No errors are defined.
