       string wcs of any  of  the  characters  in  the	wide-character	string
       reject.

       The wcscspn function returns the number of wide characters in the longest

       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
