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1.这本书页数不多。但侧重点也不多，从目录可以看出，它不像APUE一样，对*nix系统编程做了全面的描述。但对于书中所包含的IO,Memory,Process Control等系统都有较为深入的讲解。 2.IO相关的章节是这本书的亮点 3.与APUE相比，APUE更像是告诉你，事物究竟是什么，然后你来做，而...
评分没觉得有多特别，后来发现LKD也是作者的作品，所以静下心来读，这书还是很不错的。 买了一堆Unix编程的书，都没有好好读过。 这次要看完这本。加油。
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...

用户评价
对一个一直在应用层开发的工程师来说，如果对系统层有好奇心，可以读读这本书，有些东西就很明显了。很棒。
评分看看作者的大名，你就知道了。。。。。
评分还是很不错的，关于GCC拓展部分很有用
评分不厚道，简直就一本man手册,不过只看电子书还不错。。
评分对照着中文版，读了一部分。英文原版还是很好的，中文翻译实在太渣，两个版本都渣得令人发指
