ter string reject.

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.
