دانلود کتاب VAX/VMS Internals and Data Structures

This book explains how the VAX/VMS executive works. It describes the data structures maintained and manipulated by the VMS operating system, discusses the mechanisms that transfer control between user processes and the
VMS operating system (and among the components of the operating system itself), and describes some of the features of the VAX hardware as they are
used by the VMS operating system. It also describes the VMS executive, including all the major components of the executive, as well as system initialization and the operation of all system services. It does not include a general discussion of the I/O subsystem, because that subject is already described in the VAX/VMS Guide to Writing a Device Driver (Digital Equipment Corporation, 1982). However, the details of some VAX/VMS device drivers, as well as the operations of I/O-related system services are included in this book.

This book is intended for system programmers and other users of the VAX/VMS operating system who wish to understand the internal workings of the
executive. The detailed description of data structures should help system managers make better informed decisions when they configure systems for space-or time-critical applications. It will also help application designers to appreciate the effects (in speed or in memory consumption) of different design and implementation decisions.
This book assumes that the reader is familiar with the VAX architecture and the VMS operating system, particularly with its use of system services and its techniques of memory management.
