XtSetLanguageProc(3Xt) XT FUNCTIONS XtSetLanguageProc(3Xt)
XtSetLanguageProc - set the language procedure
Widget XtSetLanguageProc(XtAppContext app_context, XtLangu-
ageProc proc, XtPointer client_data);
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
Specifes addional client data to be passed to the
language procedure when it is called.
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:
+ 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.
+ 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''.
+ 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 XtDisplayIn-
itialize.
