Microsoft documents only a small fraction of Windows 2000's internals, and the information Microsoft leaves out is of immense value to system-level developers. In Undocumented Windows 2000 Secrets, Sven Schreiber tears away the veil, exposing the portions of Windows 2000 that system programmers care about most. Schreiber focuses on the internals of the Native API, security, symbol files, system memory, debugging, kernel-mode drivers, kernel functions, kernel objects, and object management. He introduces sophisticated techniques aimed at enabling developers to write more effective device drivers, file system extensions, and other system-level software. Coverage includes: using the Windows 2000 debugging interfaces; loading, parsing, and utilizing Windows 2000 symbol files; exploring Windows 2000 system memory; hooking calls to the user-mode subset of the Native API; and calling kernel functions from user-mode applications. You'll find a wealth of code resources for system exploration, kernel-mode programming, spying on interfaces, and much more. This book is an essential companion to Microsoft's DDK documentation.
