21 The wcscspn() function shall compute the length (in wide characters) of
22 the maximum initial segment of the wide-character string pointed to by
23 ws1 which consists entirely of wide-character codes not from the wide-
24 character string pointed to by ws2.
25
27 The wcscspn() function shall return the length of the initial substring
28 of ws1; no return value is reserved to indicate an error.
