XtAppAddActionHook(3Xt)   XT FUNCTIONS    XtAppAddActionHook(3Xt)


     XtAppAddActionHook, XtRemoveActionHook - register an action
     hook procedure


     XtActionHookId XtAppAddActionHook(XtAppContext app_context,
          XtActionHookProc proc, XtPointer client_data);

     void XtRemoveActionHook(XtActionHookId id);


               Specifies the application context.

     proc      Specifies the action hook procedure.

     num_args  Specifies the application-specific data to be
               passed to the action hook.


     XtAppAddActionHook adds the specified procedure to the front
     of a list maintained in the application context. In the
     future, when an action routine is about to be invoked for
     any widget in this application context, either through the
     translation manager or via XtCallActionProc, the action
     hohok procedures will be called in reverse order of regis-
     tration jut prior to invoking the action routine.

     Action hook procedures are removed automatically and the
     XtActionHookId s destroyed when the application context in
     which they were added is destroyed.

     XtRemoveActionHook removes the specified action hook pro-
     cedure from the list in which it was registered.
