The ACE Programmer's Guide: Practical Design Patterns for Network and Systems Programming (ACE 程式設計師指南：網路與系統程式設計的實用設計模式)

Summary

If you're designing software and systems that must be portable, flexible, extensible, predictable, reliable, and affordable, this book and the ACE toolkit will enable you to be more effective in all of these areas. Even after spending over a decade developing ACE and using it to build networked software applications, I find that I've learned a great deal from this book, and I'm confident that you will, too.
--Douglas C. Schmidt, Inventor of ACE, from the Foreword

This book is a must-have for every ACE programmer. For the beginner, it explains step-by-step how to start using ACE. For the more experienced programmer, it explains in detail the features used daily, and is a perfect reference manual. It would have saved me a lot of time if this book had been available some years ago!
--Johnny Willemsen, Senior Software Engineer, Remedy IT, The Netherlands

With a large C++ code base, we rely on ACE to enable a cross-platform client-server framework for data quality and data integration. ACE has improved our design and smoothed over OS idiosyncrasies without sacrificing performance or flexibility. The combination of online reference materials and printed "big picture" guides is indispensable for us, and The ACE Programmer's Guide earns top-shelf status in my office.
--John Lilley, Chief Scientist, DataLever Corporation

In SITA air-ground division, we are one of the major suppliers of communication services to the airline industry. We started using ACE about a year ago and are now moving most of our new communication-related development to it. I can say that using this toolkit can reduce the development and testing time by at least 50% in our type of application.
--Jean Millo, Senior Architect, SITA

The ADAPTIVE Communication Environment (ACE) is an open-source software toolkit created to solve network programming challenges. Written in C++, with the help of 30 core developers and 1,700 contributors, this portable middleware has evolved to encapsulate and augment a wide range of native OS capabilities essential to support performance-driven software systems.

The ACE Programmer's Guide is a practical, hands-on guide to ACE for C++ programmers building networked applications and next-generation middleware. The book first introduces ACE to beginners. It then explains how you can tap design patterns, frameworks, and ACE to produce effective, easily maintained software systems with less time and effort. The book features discussions of programming aids, interprocess communication (IPC) issues, process and thread management, shared memory, the ACE Service Configurator framework, timer management classes, the ACE Naming Service, and more.

The accompanying CD-ROM contains the complete ACE toolkit, including installable kits for Windows, Solaris, and HP-UX; complete reference documentation for all of the ACE classes; and source code for every example in the book.
