Threads and OpenAL


Hey everyone.
I need to find a way to have a C++ console application on linux that plays ogg files, but while its playing I can do other things, such as add/remove songs from teh playlist, etc. Bascially I need the sound being played independantly of the program, so it can be controlled at any point in time, not just when the song has finished.

Any help would be appreciated,
Thanks,
Chris.

Threads, as in your thread title are good idea. One playing, second one doing different things. The problem is with their communication - I suggest a variable, protected by a semaphore (or even mutex) that's read by the thread playing music (so it must be in a loop checking the mutex from time to time) and written by the second thread.

Heh, thanks. I figured threads would be the way to go. I should have been more specific, I know nothing about threads, does anyone know of any good sites?

Thankyou for your advice Mara, it clarified the solution a little, and set me on the right path.

Thanks,
Chris

So you're new with threads? Then you'll spend some time reading and experimenting, as threading changes the way you think about programs

Two nice tutorials (but you should still try with the examples yourself):

Thats great :-) Thankyou very much.
Threading does seem ...interesting, but very complex at first. I will give it a shot :-)

Thanks again,
Chris,
