Book Description
This book is about writing software that makes the most effective use of the system you're running on -- code that interfaces directly with the kernel and core system libraries, including the shell, text editor, compiler, debugger, core utilities, and system daemons. The majority of both Unix and Linux code is still written at the system level, and Linux System Programming focuses on everything above the kernel, where applications such as Apache, bash, cp, vim, Emacs, gcc, gdb, glibc, ls, mv, and X exist.
Written primarily for engineers looking to program (better) at the low level, this book is an ideal teaching tool for any programmer. Even with the trend toward high-level development, either through web software (such as PHP) or managed code (C#), someone still has to write the PHP interpreter and the C# virtual machine. Linux System Programming gives you an understanding of core internals that makes for better code, no matter where it appears in the stack. Debugging high-level code often requires you to understand the system calls and kernel behavior of your operating system, too.
Key topics include:
An overview of Linux, the kernel, the C library, and the C compiler
Reading from and writing to files, along with other basic file I/O operations, including how the Linux kernel implements and manages file I/O
Buffer size management, including the Standard I/O library
Advanced I/O interfaces, memory mappings, and optimization techniques
The family of system calls for basic process management
Advanced process management, including real-time processes
File and directories-creating, moving, copying, deleting, and managing them
Memory management -- interfaces for allocating memory, managing the memory you have, and optimizing your memory access
Signals and their role on a Unix system, plus basic and advanced signal interfaces
Time, sleeping, and clock management, starting with the basics and continuing through POSIX clocks and high resolution timers
With Linux System Programming, you will be able to take an in-depth look at Linux from both a theoretical and an applied perspective as you cover a wide range of programming topics.

评分仅拿我看到的,很小一部分翻译错误,来举例(整本书各种翻译问题数不胜数,不一一列举了): P202:SMT翻译成“同步线程”。SMT通常应该翻译成超线程,或者直接按字面意思翻译成“同时多线程”。“同步线程”通常指多线程的编程模型,完全两个维度的东西,相差十万八千里,很...
内容翔实,文笔流畅,即可
评分没有找到这本书的影印版或中文版,不好意思的看了电子版,相对于APUE来说,除了更轻薄以外,更新和更贴近现代 Linux 是这本书的优点。
评分作为第一本 Linux 编程书来说是不错的教材,深入浅出,介绍了一些基本概念。可以解答很多新手的疑惑。但是并不是非常深入,书中的例子都非常简单,基本是调用一下 API,动手实践方面不太行。另外是每次介绍 API 的时候都会贴很多 error 类型以及介绍,占了很大的篇幅…… 很多我都是跳过去了…… 总的来说还是一本不可多得的好书。
评分重点突出,应用与原理相结合,神书无疑了,比APUE更具可读性
评分前面 io 那部分还不错
