+.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 .
