How do I make a beep function using SDL?

Question

I want to make my SDL program sound a simple beep at a certain frequency. How do I go about doing that?

I've found a tutorial that writes to SDL's sound buffer or so, but it doesn't seem to work. (I'm using OSX "Snow Leopard")

Answer 1

The tutorial's code forgets to initialize Beeper::v and generateSamples does not work with random values of v. Try to add the line v=0; to Beeper::Beeper()
