DriverEntry's Required Responsibilities
1. 提供各個driver的entry point
Supply entry points for the driver's standard routines.
The driver stores entry points for many of its standard routines in the driver object or driver extension. Such entry points include those for the driver's AddDevice routine, dispatch routines, StartIo routine, and Unload routine. For example, a driver would set the entry points for its AddDevice, DispatchPnP, and DispatchPower routines with statements like the following (Xxx is a placeholder for a vendor-supplied prefix identifying the driver):
