StreamClassStreamNotification function (strmini.h)

  • Article

Streams use the StreamClassStreamNotification routine to notify the class driver that it has completed a stream request, or that an event has occurred.

  [in] STREAM_MINIDRIVER_STREAM_NOTIFICATION_TYPE NotificationType,
  [in] PHW_STREAM_OBJECT                          StreamObject,
       ...                                        
);
