       wcscspn - search a wide-character string for any of a set of wide char-
       acters

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-charac-
       ters  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.
