       XtSetLanguageProc - set the language procedure

       Widget XtSetLanguageProc(XtAppContext app_context, XtLanguageProc proc,
	      XtPointer	client_data);

		 Specifies the application context in which the	language pro-
		 cedure	is to be used, or NULL.

       proc	 Specifies the language	procedure, or NULL.

		 Specifies additional client data to be	passed to the language
		 procedure when	it is called.

       XtSetLanguageProc sets the language procedure that will be called from
       XtDisplayInitialize for all subsequent Displays initialized in the
       specified application context. If app_context is	NULL, the specified
       language	procedure is registered	in all application contexts created by
       the calling process, including any future application contexts that may
       be created. If proc is NULL a default language procedure	is registered.
       XtSetLanguageProc returns the previously	registered language procedure.
       If a language procedure has not yet been	registered, the	return value
       is unspecified but if this return value is used in a subsequent call to
       XtSetLanguageProc, it will cause	the default language procedure to be

       The default language procedure does the following:

       o    Sets the locale according to the environment. On ANSI C-based sys-
	    tems this is done by calling setlocale( LC_ALL, language ).	If an
	    error is encountered a warning message is issued with XtWarning.

       o    Calls XSupportsLocale to verify that the current locale is sup-
	    ported. If the locale is not supported, a warning message is is-
	    sued with XtWarning	and the	locale is set to ``C''.

       o    Calls XSetLocaleModifiers specifying the empty string.

       o    Returns the	value of the current locale. On	ANSI C-based systems
	    this is the	return value from a final call to setlocale( LC_ALL,
	    NULL ).

       A client	wishing	to use this mechanism to establish locale can do so by
       calling XtSetLanguageProc prior to XtDisplayInitialize.
