Kbfiltr Driver Reference
This section includes the following topics about Kbfiltr, the sample upper-level keyboard filter driver in the MSDN Code Gallery:
Kbfiltr is designed to be used with Kbdclass, the system class driver for keyboard devices that are used with Windows 2000 and later versions, and I8042prt, the function driver for a PS/2-style keyboard used with Windows 2000 and later versions. Kbfiltr demonstrates how to filter I/O requests and how to add callback routines that modify the operation of Kbdclass and I8042prt.
