regestering a filter device driver !?
#define FILE_DEVICE_RECO 0x00009000
#define RECO_MULDRV (ULONG) CTL_CODE( FILE_DEVICE_RECO, 0x00,
METHOD_BUFFERED, FILE_ANY_ACCESS )
where am i suppose to register this number 0x00009000
that is if I should, or from where can I take numbers that are not
occupied
by another device driver and also register mine.
