This is a thoroughly revised edition of the best-selling guide to UNIX software development in C for professional programmers and students. The book focuses on the UNIX system call interface, the programming interface between the UNIX Kernel and applications software running in the UNIX environment. The techniques required by systems programmers are developed in depth, illustrated by a wealth of examples.

From the Back Cover

The UNIX operating system has become a key part of the technology landscape as we move into the 21st century. There are now a huge number of large-scale data management and transaction-processing systems built on UNIX platforms, and UNIX is at the core of the server backbone of the Internet. 'The new edition of this highly successful book for professional programmers provides a lucid and well structured guide to developing UNIX software in the C language, and has been updated to reflect the more distributed environments typical of current IT solutions.

UNIX System Programming concentrates on a detailed study of the UNIX system call interface - the programming interface between the UNIX kernel and application software running in the UNIX environment - and additionally covers some of the more important subroutine libraries.

From a wealth of experience of developing system and application software, and a real appreciation of the needs of UNIX system programmers, the authors fully appreciate that computing is not a spectator sport. By exploring both system calls and subroutine libraries they give the reader a practical appreciation of when not to re-invent the wheel, as well as a better understanding of the internal workings of this still elegant operating system.
