Full Description
The Windows 2000 Device Driver Book can lead any experienced Windows programmer through every step of device driver development: planning, implementation, testing, debugging, installation, and distribution. Thoroughly updated to reflect Microsoft's Windows Driver Model (WDM) for Windows 2000 and 98, it covers everything from architecture to tools, and includes a powerhouse library of exclusive tools and C and C++ code for streamlining device driver projects. Starting with a high-level overview of WDM components, the book quickly moves into the details of the development environment and driver installation. Master the I/O Manager, its data structures, and its interaction with drivers. Understand Plug and Play and Power Management through extensive practical examples; learn how to construct safe reentrant driver code; log errors and events using Windows Management Instrumentation; utilize kernel-mode threads; layered drivers; and more. The accompanying CD-ROM includes sample drivers, C++ classes to jumpstart your projects, driver installation utilities, even an exclusive device driver AppWizard!
