NAME         top

       wcscspn  -  search  a  wide-character string for any of a set of wide
       characters

SYNOPSIS         top

       #include <wchar.h>

       size_t wcscspn(const wchar_t *wcs, const wchar_t *reject);

DESCRIPTION         top

       The wcscspn() function is the wide-character equivalent of the
       strcspn(3) function.  It determines the length of the longest initial
       segment of wcs which consists entirely of wide-characters not listed
       in reject.  In other words, it searches for the first occurrence in
       the wide-character string wcs of any of the characters in the wide-
       character string reject.

RETURN VALUE         top

       The wcscspn() function returns the number of wide characters in the
       longest initial segment of wcs which consists entirely of wide-
       characters not listed in reject.  In other words, it returns the
       position of the first occurrence in the wide-character string wcs of
       any of the characters in the wide-character string reject, or
       wcslen(wcs) if there is none.
