A user-mode driver is started by the Driver Manager and runs in a driver host process. A single instance of the driver can service simultaneous requests from multiple applications. To communicate with the driver, applications issue I/O requests to the driver’s device through the Win32 API. The primary entry point in a user-mode driver is the IDriverEntry interface, rather than a main() function.
