"This is the definitive reference book for any serious or professional UNIX systems programmer. Rago has updated and extended the classic Stevens text while keeping true to the original. The APIs are illuminated by clear examples of their use. He also mentions many of the pitfalls to look out for when programming across different UNIX system implementations and points out how to avoid these pitfalls using relevant standards such as POSIX 1003.1, 2004 edition and the Single UNIX Specification, Version 3." --Andrew Josey, Director, Certification, The Open Group, and Chair of the POSIX 1003.1 Working Group
