I am sure this has been asked before, but I couldn't find a solution or a hint via Google: I use a separate thread to play a sound file. Everything works fine, except that I cannot tell the thread to stop what it is doing. It refuses to receive messages while it is doing what it's doing (even if I just run a simple test function with a long for-loop to make sure it's not a hardware issue). I should probably add that the thread is started from within the main loop of a socket that waits for input. If the input is "stop" it should tell the play-thread to stop, but nothing happens. I can imagine that the thread is no longer visible to the main-thread, although I keep a reference to it. Any help or hint will be appreciated.
Wild guess: sounds likely that your "play thread" does some blocking processing and just never pauses to process messages. You need to explicitly say to the thread when to have a pause in a job and check incoming messages. You can kill the thread externally but that would be an abnormal termination, no destructors called and all the bad stuff.
That said, I assume some typical pthread-based code, details may differ depending on the implementation.
