+.Sh NAME
+.Nm newlocale
+.Nd Creates a new locale 
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In xlocale
+.Ft 
+.Fn newlocale "int mask" "const char * locale" "locale_t base"
+.Sh DESCRIPTION
+Creates a new locale, inheriting some properties from an existing locale.  The
+.Fa mask 
+defines the components that the new locale will have set to the locale with the
+name specified in the 
+.Fa locale
+parameter.  Any other components will be inherited from
+.Fa base .
+.Pt
+The
+.Fa mask
+is either
+.Fa LC_ALL_MASK,
+indicating all possible locale components, or the logical OR of some
+combination of the following:
+.Bl -tag -width "LC_MESSAGES_MASK" -offset indent
+.It LC_COLLATE_MASK
+The locale for string collation routines.  This controls alphabetic ordering in
+.Xr strcoll 3
+ and 
+.Xr strxfrm 3 .
+.It LC_CTYPE_MASK
+The locale for the
+.Xr ctype 3
+and
+.Xr multibyte 3
+functions.  This controls recognition of upper and lower case, alpha- betic or
+non-alphabetic characters, and so on.
+.It LC_MESSAGES_MASK
+Set a locale for message catalogs, see
+.Xr catopen 3
+function.
+.It LC_MONETARY_MASK
+Set a locale for formatting monetary values; this affects
+the
+.Xr localeconv 3
+function.
+.It LC_NUMERIC_MASK
+Set a locale for formatting numbers.  This controls the for-
+matting of decimal points in input and output of floating
+point numbers in functions such as
+.Xr printf 3
+and
+.Xr scanf 3 ,
+as well as values returned by
+.Xr localeconv 3 .
+.It LC_TIME_MASK
+Set a locale for formatting dates and times using the
+.Xr strftime 3
+function.
+.El
+
+This function uses the same rules for loading locale components as
+.Xr setlocale 3 .
+.Sh RETURN VALUES
+Returns a new, valid,
+.Fa locale_t
+or NULL if an error occurs.  You must free the returned locale with
+.Xr freelocale 3 .
+.Sh SEE ALSO
