DriverUnload: deinitialization code that cleans after the driver when it's no longer needed, which usually happens when a certain service is stopped. The three methods are “Direct I/O”, “Buffered I/O” and “Neither”.#ifdef __USE_DIRECT__ #define IO_TYPE DO_DIRECT_IO #define USE_WRITE_FUNCTION Example_WriteDirectIO #endif #ifdef __USE_BUFFERED__ #define IO_TYPE DO_BUFFERED_IO #define USE_WRITE_FUNCTION Example_WriteBufferedIO #endif #ifndef IO_TYPE #define IO_TYPE Both of these will generate a PE binary with the appropriate subsystem information. I will not attempt to duplicate this information nor point out every single little detail.

Kernel APIs documented in MSDN generally have a note which specifies the IRQL level at which you need to be running in order to use the API. Interrupts with smaller IRQL levels are temporarily disabled. The code above should be pretty easy to understand that you need to copy the driver to C:\example.sys in order to use it. There are a variety of different types of drivers which operate at different levels, not all drivers work or interface directly with hardware.

I know that a lot of people simply want to jump right into writing the driver and seeing it work. There is no graphical interface to the DDK compiler. USE_WRITE_FUNCTION is a constant I will explain later. are all examples of this.

I would advise you at this stage to use the OSR Driver Loader to register your driver. When a processor is executing code in a particular IRQL level, that code can be interrupted only by those with higher IRQL levels on the same processor.
