Your application probably didn’t work right away, probably crashed, or just disappeared.

Direct I/O The first thing I will do is simply show you the code for handling direct I/O.NTSTATUS Example_WriteDirectIO(PDEVICE_OBJECT DeviceObject, PIRP Irp) { NTSTATUS NtStatus = STATUS_SUCCESS; PIO_STACK_LOCATION pIoStackIrp = NULL; The highest level may interpret them as file data, but the lowest level driver may simply be stupid and only manage requests as far as when to read a sector based Create the DriverEntry routine There is so much to explain, however, I think it’s time we simply started to develop the driver and explain as we go.
