The
wcscspn function is the wide-character equivalent of the
strcspn 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.
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

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.
