size_t wcscspn(const wchar_t *ws1, const wchar_t *ws2);
The wcscspn() function shall compute the length (in wide characters) of the maximum ini-

wide-character codes not from the wide-character string pointed to by ws2.
The wcscspn() function shall return the length of the initial substring of ws1; no return
value is reserved to indicate an error.
No errors are defined.
