XtCallActionProc()					    XtCallActionProc()

Name
  XtCallActionProc - explicitly invoke a named action procedure.

Synopsis
  void XtCallActionProc(widget, action, event, params, num_params)
	   Widget widget;
	   String action;
	   XEvent *event;
	   String *params;
	   Cardinal num_params;

Inputs
  widget    Specifies  the  widget  in which the action is to be invoked;
	    must be of class Core or any subclass thereof.

  action    Specifies the name of the action routine.

  event	    Specifies the event to pass to the action procedure.

  params    Specifies parameters to pass to the action procedure.

  num_params
	    Specifies the number of elements in the params array.

Description
  XtCallActionProc() looks up  the  action  procedure  named  action  and
  invokes it, passing widget, event, params, and num_params as arguments.
  Before calling the named action, XtCallActionProc() invokes any  action
  hook procedures that have been registered with XtAppAddActionHook().

  It  is  the responsibility of the caller to ensure that the contents of
  the event, params, and num_params arguments  are  appropriate	 for  the
  specified  action  routine and, if necessary, that the specified widget
  is realized and/or sensitive.	 If the named action  routine  cannot  be
  found, XtCallActionProc() generates a warning message and returns.

  When	searching  for	the action procedure, XtCallActionProc() looks in
  the following places:

  ·  The widget's class and all superclass action tables, in subclass-to-
     superclass order.

  ·  The parent's class and all superclass action tables, in subclass-to-
     superclass order, then on up the ancestor tree.

  ·  The action tables registered  with	 XtAppAddActions()  and	 XtAddAc‐
     tions() from the most recently added table to the oldest table.
