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.
