DESCRIPTION
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 at
only the first maxlen
wide characters at s
and never beyond s+maxlen.
RETURN VALUE
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.
