UNIX环境高级编程第三版(英文文字原版)，干净，不含任何额外信息，链接之流。
简介：
This book describes the programming interface to the Unix system—the system call interface and many of the functions provided in the standard C library. It is intended for anyone writing programs that run under Unix.
Like most operating systems, Unix provides numerous services to the programs
that are running — open a file, read a file, start a new program, allocate a region of memory, get the current time-of-day, and so on. This has been termed the system call interface. Additionally, the standard C library provides numerous functions that are used by almost every C program (format a variable's value for output, compare two strings, etc.).
The system call interface and the library routines have traditionally been described in Sections 2 and 3 of the Unix Programmer 's Manual. This book is not a duplication of these sections. Examples and rationale are missing from the Unix Programmer's Manual, and that's what this book provides.
本书章节安排如下：
1. An overview and introduction to basic Unix programming concepts and
terminology (Chapter 1), with a discussion of the various Unix standardization
efforts and different Unix implementations (Chapter 2).
2. I/O—unbuffered I/O (Chapter 3), properties of files and directories
(Chapter 4), the standard I/O library (Chapter 5), and the standard system data
files (Chapter 6).
3. Processes — the environment of a Unix process (Chapter 7), process control
(Chapter 8), the relationships between different processes (Chapter 9), and
signals (Chapter 10).
4. More I/O — terminal I/O (Chapter 11), advanced I/O (Chapter 12), and daemon
processes (Chapter 13).
5. IPC—Interprocess communication (Chapters 14 and 15).
6. Examples—a database library (Chapter 16), communicating with a PostScript
printer (Chapter 17), a modem dialing program (Chapter 18), and using pseudo
terminals (Chapter 19).
对于Unix编程手册，绝大多其他的同类书籍都会以此类为蓝本，进行扩展延伸，本书也不例外。本书是面向C编程的，Unix/Linux编程实践（Understanding Unix-Linux Programming）会是预备书。
