TCP/IP C Sockets
TCP/IP Sockets In C 第二版 英文版 Changes from the First Edition We have updated and considerably expanded most of the material, having added two chapters. Major changes from the first edition include: IP version 6 coverage. We now include three kinds of code: IPv4-specific, IPv6-specific, and generic. The code in the later chapters is designed to work with either protocol version on dual-stack machines. An additional chapter on socket programming in C++ (contributed by David B. Sturgill). The PracticalSocket library provides wrappers for basic socket functionality. These allow an instructor to teach socket programming to students without C programming back- ground by giving them a library and then gradually peeling back the layers. Students can start developing immediately after understanding addresses/ports and client/server. Later they can be shown the details of socket programming by peeking inside the wrapper code. Those teaching a subject that uses networking (e.g., OS) can use the library and only selectively peel back the cover. Enhanced coverage of data representation issues and strategies for organizing code that sends and receives messages. In our instructional experience, we find that students have less and less understanding of how data is actually stored in memory, 1 so we have attempted to compensate with more discussion of this important issue. At the same time, internationalization will only increase in importance, and thus we have included basic coverage of wide characters and encodings. Omission of the reference section. The descriptions of most of the functions that make up the Sockets API have been collected into the early chapters. However, with so many online sources of reference information—including “man pages”—available, we chose to leave out the complete listing of the API in favor of more code illustrations. Highlighting important but subtle facts and caveats. Typographical devices call out important concepts and information that might otherwise be missed on first reading. Although the scope of the book has expanded, we have not included everything that we might have (or even that we were asked to include); examples of topics left for more comprehensive texts (or the next edition) are raw sockets and programming with WinSock.
