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_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 pro-cedure. procedure.
       cedure. 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 lan-guage language
       guage 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
            XtWarning.

       •    Calls XSupportsLocale to verify that the current locale is supported. If the locale is not sup-ported, supported,
            ported, 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 setlocale( LC_ALL, NULL ).

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