XtCreateApplicationContext(3Xt)      SysV      XtCreateApplicationContext(3Xt)



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 application context,
     which is an opaque type.  Every application must have at least one
     application context.

     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 semantics of calling XtToolkitInitialize more than once are
     undefined.
