-.fi
-.SH DESCRIPTION
-The
-.BR wcsnlen ()
-function is the wide-character equivalent
-of the
-.BR strnlen (3)
-function.
-It returns the number of wide-characters in the string pointed to by
-.IR s ,
-not including the terminating null wide character (L\[aq]\e0\[aq]),
-but at most
-.I maxlen
-wide characters (note: this parameter is not a byte count).
-In doing this,
-.BR wcsnlen ()
-looks at only the first
-.I maxlen
-wide characters at
-.I s
-and never beyond
-.IR s[maxlen\-1] .
-.SH RETURN VALUE
-The
-.BR wcsnlen ()
-function returns
-.IR wcslen(s) ,
-if that is less than
-.IR maxlen ,
-or
-.I maxlen
-if there is no null wide character among the
-first
-.I maxlen
-wide characters pointed to by
-.IR s .
