XtSetLanguageProc(3)			   XT FUNCTIONS 		     XtSetLanguageProc(3)

NAME
       XtSetLanguageProc - set the language procedure

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

ARGUMENTS
       app_context
		 Specifies the application context in which the language procedure is to be used,
		 or NULL.

       proc	 Specifies the language procedure, or NULL.

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

DESCRIPTION
       XtSetLanguageProc sets the language procedure that will be called from XtDisplayInitialize
       for all subsequent Displays initialized in the specified application context. If app_con-
       text 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 cre-
       ated. 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
       registered.

       The default language procedure does the following:

       o    Sets the locale according to the environment. On ANSI C-based systems 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 supported. If the locale
	    is not supported, a warning message is issued 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 XtSet-
       LanguageProc prior to XtDisplayInitialize.
