Written by the former Chair of the ANSI C committee, this book is an alphabetized quick reference guide to C. It contains concise definitions with extensive cross-referencing to other entries and, in some cases, a small amount of tutorial material. Many entries describe library functions. A table of punctuation characters assigns a corresponding English word or phrase that is the primary entry in the dictionary for that symbol.
it is suitable for all levels of C programmers and includes a broad range of subject matter including advanced topics. Because it does not deal with extensions, it is not aimed at any particular kind of application or set of platforms: it is generic and is applicable to anyone working with C using any mainstream implementation of C.
