       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-char-
       acter 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.
