void XtDestroyApplicationContext(app_context)
XtAppContext app_context;
XtAppContext XtWidgetToApplicationContext(w)
Widget w;
void XtToolkitInitialize()
The XtDestroyApplicationContext function destroys the specified application context as soon as it is safe to do so. If called from with an event dispatch (for example, a callback procedure), XtDestroyApplicationContext does not destroy the application context until the dispatch is complete.
The XtWidgetToApplicationContext function returns the application context for the specified widget.
The XtToolkitInitialize function initializes the Intrinsics internals. If XtToolkitInitialize was previously called it returns immediately.
