520			_aUNIX Programming is designed to enable the reader to get the most out of the UNIX programming libraries. It will show the reader how to master the UNIX static and runtime libraries, to develop creative designs, and write successful, portable code. It provides the reader with the capability of building programming strength under UNIX by providing solid code examples. The organization of the material will make it a useful reference tool. Some topics covered that are often missing from UNIX programming books are: -- xWindow programming -- Regular Expression Matching -- Memory Mapped Files -- DBM database library routines Sams White Books present high-level expertise for a professional audience. The books explain what the technology is and how it can be used rather than how it is supposed to work. Workarounds are always explored if necessary. The advice, code and examples all reflect practical, realistic ways for solving problems.
