XtSetLanguageProc(3Xt) XT FUNCTIONS XtSetLanguageProc(3Xt)NAMEXtSetLanguageProc - set the language procedure
SYNTAX
Widget XtSetLanguageProc(app_context, proc, client_data)
XtAppContext app_context;
XtLanguageProc 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
Specifes addional client data to be passed to
the language procedure when it is called.
DESCRIPTIONXtSetLanguageProc sets the language procedure that will be
called from XtDisplayInitialize for all subsequent Dis-
plays 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 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 subse-
quent call to XtSetLanguageProc, it will bcause the
default language procedure to be registered.
The default language procdure 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
warning 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 setlocal( LC_ALL, NULL ).
A client wishing to use this mechanism to establish locale
can do so by calling XtSetLanguageProc prior to XtDis-
playInitialize.
