NAME
       XtAppAddActionHook, XtRemoveActionHook - register an action hook procedure

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

       void XtRemoveActionHook(idFP)
	       XtActionHookId id;

ARGUMENTS
       Specifies  the  application  context.   Specifies  the  action hook procedure.  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 context, either through the translation manager or via XtCallActionProc,
       the action hook procedures will be called in reverse order of registration just prior to invoking the action routine.

       Action hook procedures are removed automatically and the XtActionHookId is 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.
