  27 /*  FUNCTION
  28         For custom class implementors. Valid between MUIM_Setup/MUIM_Cleanup.
  29         Indicates that this object wants to receive some events. MUIM_HandleInput
  30         will then be called on this object whenever there's a matching event.
  31
  32     INPUTS
  33         obj   - an object whose class is derived from Area
  34         flags - IDCMP flags
  35
  36     RESULT
  37         None.
  38
  39     NOTES
  40         Deprecated in favor of MUIM_Window_AddEventHandler and MUIM_HandleEvent
  41         event handling model (introduced in MUI V16).
