XtCallActionProc - invoke an action procedure directly

widget    Specifies the widget in which the action is to be invoked.   Must  be  of  class  core  of  any
                 subclass thereof.

       action    Specifies the name of the action routine.

       event     Specifies the contents of the event passed to the action routine.

       params    Specifies the contents of the params passed to the action routine.

       num_params
                 Specifies the num of entries in params.

XtCallActionProc searches for the named action routine in the same manner and order as translation tables
       are  bound.   If  found,  the  action  routine  is  invoked with the specified widget, event pointer, and
       parameters.  It is the responsibility of the caller to ensure that the contents  of  event,  params,  and
       num_params  arguments  are  appropriate  for  the specified routine, and if necessary, that the specified
       widget is realized or sensitive.  If the named action routine cannot be found, XtCallActionProc generates
       a warning message and returns.
