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 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-characters 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
