NAME

12       wcscspn - get the length of a complementary wide substring
13

SYNOPSIS

DESCRIPTION

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

RETURN VALUE

27       The wcscspn() function shall return the length of the initial substring
28       of ws1; no return value is reserved to indicate an error.
