+Duplicates an existing
+.Fa locale_t
+returning a new
+.Fa locale_t
+that refers to the same locale values but has an independent internal state.
+Various functions, such as
+.Xr mblen 3
+require a persistent state.
+These functions formerly used static variables and calls to them from multiple
+threads had undefined behavior.
+They now use fields in the
+.Fa locale_t
+associated with the current thread by
+.Xr uselocale 3 .
+These calls are therefore only thread safe on threads with a unique per-thread
+locale.
+The locale returned by this call must be freed with
+.Xr freelocale 3 .

+.Sh STANDARDS
+This function conforms to
+.St -p1003.1-2008 .
+.Sh BUGS
+Ideally,
+.Xr uselocale 3
+should make a copy of the
+.Fa locale_t
+implicitly to ensure thread safety,
+and a copy of the global locale should be installed lazily on each thread.
+The FreeBSD implementation does not do this,
+for compatibility with Darwin.

+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In locale.h
+.Ft locale_t
+.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 components not specified in
+.Fa mask
+will be inherited from the locale referenced by
+.Fa base ,
+if
+.Fa base
+is not
+.Dv NULL .
+If the call is successful, the state of the locale referenced by
+.Fa base
+is unspecified, and it must not be accessed.
+The special locale
+.Dv LC_GLOBAL_LOCALE
+may not be specified for
+.Fa base .
+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, alphabetic 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 formatting 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
+.Xr duplocale 3 ,
+.Xr freelocale 3 ,
