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.
