The strength of this book is it's brevity: 233 pp of text plus appendices. But the code samples are incomplete (fragments). You'll be able to get an idea of how pthreads work and the methods available, but you'll have a very hard time if you need to actually write code. There is an error on p.126. If you want to write code, get "Programming with POSIX Threads" by David Butenhof. It has complete code examples and is not that much longer: 305 pp of text plus appendices. But I did find this Nichols book helpful when I was curious about pthreads. I commend O'Reilly for the nice illustrations in this book -- above average. They helped convey concepts.

As usual, O'Reilly have produced an excellent reference book. In a few respects, this book is preferable to Scott Norton's "Thread Time" - it has better examples, for one.
But this book is not as detailed or complete as Norton, so I don't recommend it as the best choice on the subject.

Of the 4 I've read on the topic, this is a good book but my personal preference (based on how the information was presented, the relevance of coding examples, etc.) is for the Butenhof Pthreads book (excellent) or the Lewis, et. al. Multithreaded Programming book (also very good).
