NAME
       wcscspn - search a wide-character string for any of a set of wide char‐
       acters

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	 strc‐
       spn() 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.
