.SH NAME
XtSetLanguageProc \- set the language procedure
.SH SYNTAX
.HP
Widget XtSetLanguageProc(XtAppContext \fIapp_context\fP, XtLanguageProc
\fIproc\fP, XtPointer \fIclient_data\fP);
.SH ARGUMENTS
.IP \fIapp_context\fP 1i
Specifies the application context in which the language procedure
is to be used, or NULL.
.LP
.IP \fIproc\fP 1i
Specifies the language procedure, or NULL.
.LP
.IP \fIclient_data\fP 1i
Specifies additional client data to be passed to the language procedure
when it is called.
.SH DESCRIPTION
.ZN XtSetLanguageProc
sets the language procedure that will be called from
.ZN XtDisplayInitialize
for all subsequent Displays initialized in the specified application
context. If \fIapp_context\fP 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
\fIproc\fP is NULL a default language procedure is registered.
.ZN 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
.ZN XtSetLanguageProc ,
it will cause the default language procedure to be registered.
.LP
The default language procedure does the following:
.IP \(bu 5
Sets the locale according to the environment. On ANSI C-based systems
this is done by calling
.ZN setlocale (
.ZN LC_ALL ,
language ). If an error is encountered a warning message is issued with
.ZN XtWarning .
.IP \(bu 5
Calls
.ZN XSupportsLocale
to verify that the current locale is supported. If the locale is not
supported, a warning message is issued with
.ZN XtWarning
and the locale is set to ``C''.
.IP \(bu 5
Calls
.ZN XSetLocaleModifiers
specifying the empty string.
.IP \(bu 5
Returns the value of the current locale. On ANSI C-based systems this
is the return value from a final call to
.ZN setlocale (
.ZN LC_ALL ,
NULL ).
.LP
A client wishing to use this mechanism to establish locale can do so
by calling
.ZN XtSetLanguageProc
prior to
.ZN XtDisplayInitialize.
