NAME
       XtAppAddActionHook, XtRemoveActionHook - register an action hook pro-
       cedure

SYNTAX
       XtActionHookId XtAppAddActionHook(XtAppContext app_context, XtAction-
	      HookProc proc, XtPointer client_data);

       void XtRemoveActionHook(XtActionHookId id);

ARGUMENTS
       app_context
		 Specifies the application context.

       proc	 Specifies the action hook procedure.

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

DESCRIPTION
       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 con-
       text, 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 XtAction-
       HookId s destroyed when the application context in which they were
       added is destroyed.

       XtRemoveActionHook removes the specified action hook procedure from
       the list in which it was registered.
