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(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-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.

CONFORMING TO

       C99.
