NAME

       XtSetLanguageProc - set the language procedure

SYNOPSIS

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

ARGUMENTS

       Specifies  the  application  context  in  which	the language procedure is to be used, or NULL.	Specifies the language procedure, or NULL.
       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 reg-
       istered.   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 because	the  default  lan-
       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 ver-
       ify  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".	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.
