Every programmer and software project manager must master the art of creating reusable software modules; they are the building blocks of large, reliable applications. Unlike some modern object-oriented languages, C provides little linguistic support or motivation for creating reusable application programming interfaces (APIs). While most C programmers use APIs and the libraries that implement them in almost every application they write, relatively few programmers create and disseminate new, widely applicable APIs. C Interfaces and Implementations shows how to create reusable APIs using interface-based design, a language-independent methodology that separates interfaces from their implementations. This methodology is explained by example. The author describes in detail 24 interfaces and their implementations, providing the reader with a thorough understanding of this design approach.
David R. Hanson is a Professor of Computer Science at Princeton University with more than 20 years of research experience in programming languages. He has conducted research in conjunction with Bell Laboratories and is the co-author of lcc, a production quality, research compiler for the C language that is popular with the Unix community. lcc is presented and analyzed in the book A Retargetable C Compiler: Design and Implementation, by Christopher Fraser and David Hanson (c) 1995, Addison-Wesley. 0201498413AB04062001
