NAME
     XtCreateApplicationContext, XtDestroyApplicationContext,
     XtWidgetToApplicationContext, XtToolkitInitialize - create,
     destroy, and obtain an application context

SYNTAX
     XtAppContext XtCreateApplicationContext()

     void XtDestroyApplicationContext(app_context)
           XtAppContext app_context;

     XtAppContext XtWidgetToApplicationContext(w)
           Widget w;

     void XtToolkitInitialize()

ARGUMENTS
     app_context
               Specifies the application context.

     w         Specifies the widget .

DESCRIPTION
     The XtCreateApplicationContext function returns an applica-
     tion context, which is an opaque type.  Every application
     must have at least one application context.

     The XtDestroyApplicationContext function destroys the speci-
     fied 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 appli-
     cation context for the specified widget.

     The semantics of calling XtToolkitInitialize more than once
     are undefined.
