is to be used, or NULL.
|

|

.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,
|
2012-03-10 09:45:48 -07:00
|
|
|
including any future application contexts that may be created. If
|
2006-11-25 11:01:46 -07:00
|
|
|
\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.
|
|
|
|
|

|

|
|
|
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

|

|
|
|
.ZN XSupportsLocale
|
2006-11-25 11:01:46 -07:00
|
|
|
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''.
|
|
|

|
|
|
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 (
|
|

A client wishing to use this mechanism to establish locale can do so

|
|
by calling
