Using This Book
This text can be used as either a tutorial on
network programming or as a reference for experienced programmers.
When used as a tutorial or for an introductory class on network
programming, the emphasis should be on Part 2, "Elementary Sockets"
(Chapters 3
through 11), followed by whatever
additional topics are of interest. Part 2 covers the basic socket
functions for both TCP and UDP, along with SCTP, I/O multiplexing,
socket options, and basic name and address conversions. Chapter 1 should be
read by all readers, especially Section 1.4, which
describes some wrapper functions used throughout the text.
Chapter 2
and perhaps Appendix A should be referred to
as necessary, depending on the reader's background. Most of the
chapters in Part 3, "Advanced Sockets," can
be read independently of the others in that part of the book.
To aid in the use of this book as a reference, a
thorough index is provided, along with summaries on the end papers
of where to find detailed descriptions of all the functions and
structures. To help those reading topics in a random order,
numerous references to related topics are provided throughout the
text.
