Chapter 5
Device Interfaces
This chapter explains how to use device interfaces to make a driver available to the kernel and Win32 user-mode applications. The device interface code in the Wdm1 driver is described. The example Wdm1Test user-mode program shows how to use the Win32 functions to find device interfaces. Wdm1Test then sends some basic I/O requests to the Wdm1 driver.
