XtSetLanguageProc(3Xt)		 XT FUNCTIONS	       XtSetLanguageProc(3Xt)



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 pro-
		 cedure is to be used, or NULL.


       proc	 Specifies the language procedure, or NULL.


       client_data
		 Specifes addional 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_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 regis-
       tered.  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 sub-
       sequent call to XtSetLanguageProc, it will cause the default language
       procedure to be registered.

       The default language procedure does the following:

       ·    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 XtWarn-
	    ing.

       ·    Calls XSupportsLocale to verify that the current locale is sup-
	    ported. If the locale is not supported, a warning message is
	    issued with XtWarning and the locale is set to ‘‘C’’.

       ·    Calls XSetLocaleModifiers specifying the empty string.

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

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