Prentice Hall's most important C programming title in years. A companion volume to Kernighan & Ritchie's C PROGRAMMING LANGUAGE. A collection of reusable functions (code for building data structures, code for performing math functions and scientific calculations, etc.) which will save C programmers time and money especially when working on large programming projects. The C Library is part of the ANSI (American National Standard Institute) for the C Language. This new book contains the complete code for the library. It covers elements of the library with which even the most experienced C programmers are not familiar such as internationalization (the ability to write programs that can adapt to different cultural locales, for example, using the C library, programmers can write software that manipulates large character sets such as Kanji). Structured like the Standard C Library, it contains 15 headers declaring or defining all of the names in the library. A separate chapter covers each header, including excerpts from relevant portions of the C Standard showing all codes needed to implement each portion of the library and explaining why it is necessary. The book teaches readers the concepts and design issues associated with library building. Using this book, programemrs will be less likely to re-code something that already exists in a given program. Plauger is one of the world's leading experts on C and the C Library.
