DESCRIPTION

       spn(3)  function.  It determines the length of the longest initial seg
       ment 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-charac
       ter 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.
