XT FUNCTIONS                               XtSetLanguageProc(3xt)



NAME
     XtSetLanguageProc - set the language procedure

SYNTAX
     cc [ flag... ] file... -lXt [ library... ]

     Widget XtSetLanguageProc(XtAppContext app_context, XtLangu-
          ageProc 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 cal-
     ling 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 XtSet-
     LanguageProc, 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 warn-
          ing 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 XtSetLanguageProc prior to XtDisplayIn-
     itialize.
