关于C语言编程的专家建议很难找。虽然面向对象编程语言的参考帮助有很多，但针对C语言的同类信息却少得令人吃惊。通过这本实践指南，初学者和有经验的C语言程序员都能找到相关的设计决策指导，包括在构建大型程序时如何将它们循序渐进地应用于现役代码。
作为设计模式社区的主要成员，Christopher Preschern解答了如何构造C程序、应对错误处理、设计柔性接口等问题。无论你是在寻找特定的模式，还是想了解特定主题的设计选择，本书都能助你一臂之力。在第一部分中，你将学习如何实现专门针对C编程语言的实用设计知识。
第二部分包括应用C编程模式实现大型程序。你将从中学习到模式是如何通过良好的设计决策提高工作效率的。本书包括以下模式：
错误处理
返回错误信息
内存管理
从C函数返回数据
数据生命周期和所有权
柔性API
柔性迭代器接口
在模块化程序中组织文件
摆脱＃ifdel地狱

克里斯托弗·普雷斯奇，Christopher Preschern组织了设计模式会议并发起了改进模式编写的倡议。作为ABB公司的C程序员，他收集并记录了如何编写工业级代码的实践知识。他曾在格拉茨科技大学讲授编码以及代码质量的相关课程，拥有计算机科学博士学位。
