http://stackoverflow.com/questions/4989451/mutex-example-tutorial I'm new to multithreading and was trying to understand how mutexes work. Did a lot of Googling and this is the only decent tutorial.. in Windows only where the objects are faster than mutexes and are visible only to the thread which implements it. Otherwise.. some lines of code. There are concepts of recursive mutexes etc but this example was only meant to show you the basic concept...

Of course you can write multi threaded code in practice for.. . The new standard provides high level gadgets like mutexes and condition variables and it also provides low level gadgets.. some serious low level code you should probably stick to mutexes and condition variables. That's what I intend to do. For more..
