Dissecting DOS: A Code-Level Look at the DOS Operating System
The source code of MS-DOS is both secret and copyright-protected, so, as a Windows and DOS programmer, you can't study the code and figure out how this operating system works. If you could study the code, you would be able to optimize your Windows and DOS programs.Now there'sDissecting DOS, the first book to take programmers on a fantastic voyage through the code-level guts of MS-DOS. The book features the complete source code for the DOS work-alike operating system RxDOS, which emulates and parallels the commercial system.Dissecting DOSexplains the architecture, command structure, and operation of DOS and uses the work-alike RxDOS to illustrate the source code controlling vital DOS actions, such as processing function calls, file redirection, disk compression, memory management and device drivers.Dissecting DOSreveals the details of DOS:file processingmemory allocationprocess managementCOMMAND.COM functionsdevice redirectionlow level file allocation table (FAT) architecture.The book features extensive innovative techniques and technical insights for Windows and DOS programmers, such as how your program can usurp the MS-DOS COMMAND.COM component and other functions to achieve optimum customization. The accompanying disk includes the entire source code for the MS-DOS workalike RxDOS. Readers can use actual RxDOS source code in their own programs to emulate DOS functions and features.Dissecting DOSreveals the inner secrets of MS-DOS that every PC programmer needs to know.020162687XB04062001
