This book is a must own for every serious programmer on the unix platform. It provides an insight on various forms of IPC APIs available on the unix platform. It provides coverage of both System V and POSIX standards, there is no match to it as far as IPC is concerned. The Appendices in the end also provide a performance comparison between pipes, FIFOs, posix message queues, System V message queues, doors and Sun RPC. I have not seen another book provide such a wide and deep coverage of this topic. What more - it all comes from the GURU himself!

great info about pipe, shared memory. need some more work but overall good to have this book. It is sad that author of this book (GodFather of Unix) is no longer here. I learned very much from having this book. Some improvements have been made from earlier edition. This may not be the first book recommended for beginners.

When you first want to learn about IPC on Unix, its a bit hard to know where to start. This book has a great coverage of all the options available with enough information on each one to get you started.

Covers semaphores, mutexes, read write locks, record locks, message queues, pipes and shared memory with extensive examples in C.

A must have book along with Vol I for anyone dealing with network programming.

I found this book invaluable when having to port POSIX code to a SVR4 system. The examples given are obscure, but useful for a serious systems programmer. Having first referenced several other books for the same material, I found there were no comparisons once I picked up UNPv2. A *must have* reference book for Unix systems programmers!

I didn't get exactly what I needed out of this book. It's good as a reference, but I think it leaves out some information on different topics. The IPC section is a little skimpy, but then again it's not a book about IPC per se...some of the stuff the way it was written was not any more understandable than a manpage, and often you buy books hoping that they are worded less cryptically than manpages. On the upside, I got most of what I needed out of it.

Ok, I will admit to be biased. Stevens is a unix programming god. Or mine anyway.

However, I will dare say that again he has improved his previous good work. I felt that he improved and showed a lot more in his second edition of Volume I, and I felt the same way about volume II. While his was HARDLY the first serious book on thread programming that I have read (I also suggest programming with Posix Threads, if it interests you), his was very informative, from both a beginner and advanced standpoint. If you have only one author to buy, this is it.
