The wcsnlen() function is
the wide-character equivalent of the strnlen(3) function. It
returns the number of wide-characters in the string pointed
to by s, not
including the terminating null wide character (L'\0'), but at
most maxlen wide
characters (note: this parameter is not a byte count). In
doing this, wcsnlen() looks
only at the first maxlen wide characters at
s and never beyond
s+maxlen.
The wcsnlen() function
returns wcslen(s),
if that is less than maxlen, or maxlen if there is no null wide
character among the first maxlen wide characters pointed
to by s.
