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

SYNOPSIS
       #include <wchar.h>

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

DESCRIPTION
       The wcscspn function is the wide-character  equivalent  of
       the  strcspn  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
       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(n) if there
       is none.
