[linux-audio-dev] Thread programming issues, hints and links wanted

Hi there, Beginning to play with some code in linux plateform for audio, I face a major problem: I have a very weak understanding of thread programming. I know the basic concepts (thread principle, mutex and lock), but fail to use them effectively. I found a lot of links on thread programming, but it is just about the API (generally pthread), and the examples are really trivial in general. When I looked at the archive, I see a lot of terms which I don't really understand, like watchdog thread, thread scheduling, and I am lost :( So does anybody know a good and deep online ressource about thread programming ? Also, my main language is C++, and I looked a bit at boost library. It should be kind of a detail, but are there deep differences between pthread and boost.threads ? Thanks, David
