[SDL] how to use a mic in SDL???

[Maciej Szupieńko]

Hello, I am only beginer in programming in SDL. I'd like to record my voice 
and delay it, but I couldn't find nowhere how to control my sound card, 
especcially microphone. Recently I found a library called "portaudio" or 
something like that, but I can't link it to my programme. I would be very 
greatful if someonoe could tell me how to implement using mic in C++.
thanks
