Description:
Writing kernel-mode Windows NT programs--such as file-system drivers (FSDs), filter drivers, and antivirus programs--poses a challenge to even experienced Windows programmers. It's hard enough to get these programs to work, but getting them to live peacefully with other kernel programs and NT itself is an art. Nagar sorts through the mechanics of writing such programs in this book, which is no mean feat considering that Microsoft provides no documentation for its development kit. The author begins by orienting the reader to NT's kernel mode, detailing what runs there, how the various programs interact, and what you need to keep in mind when developing software for the kernel mode. The book then explores NT's key managers--I/O, virtual memory, and cache--covering the operation and exposed services for each. Nagar then takes the explanatory information he's provided and works it into a how-to guide to developing FSDs. In walking you through developing an actual FSD, the author covers I/O requests, cache operations, and buffers. Exercise files appear on the companion diskette. Short of having a live instructor, you could not ask for a better guide to this complicated subject.
