pthreads programming

I've discovered a few things in my (rather extensive) experience with pthreads.

It isn't a good idea to find a recipe to do a particular thing in pthreads, and then go do it. It's much better in the long run to get a thorough understanding of how pthreads work. The reason for this is that debugging programs using pthreads can be frustrating and time-consuming, and it is easy (if you don't know thoroughly and anally what you're doing) to write a program that's impossible to debug well.

I'd recommend that you fork over a few bucks and get David R. Butenhof's book _Programming with POSIX Threads_, published by Addison Wesley. Do _not_ get _Pthreads Programming_ from O'Reilly. It doesn't convey the deeper understanding you really need to do pthreads programming correctly.

Hope this helps.
