I admit that I had not considered that way of using volatile in C++ to prevent inadvertent unlocked accesses. That seems like a good idea. I was thinking about applying volatile to primitive types, and indeed the article agrees with me: don't do it for multithreaded code. Thanks for the pointer to the article.

I've recently started working on some multi threaded C++ apps. Currently using Trolltech/Qt's libraries but I'll probably also probably use Boost. Anyway, this discussion of volatile was very helpful, especially the use of volatile sig_atomic_t as a signal which will not require a semaphore or mutex. At any rate, I'm curious about your view of this use of volatile, from Andrei Alexandrescu. http://www.ddj.com/cpp/184403766 It seems incorrect or at least unintended according to the standard. However, I have used it on a small project and had good results. Thanks! Hi Ian. Thanks for this post. I’ve recently started working on some multi threaded C++ apps.
