[linux-audio-dev] Howto grab keys?

Hello, I'm using PortAudio library to try to program a loop-sampler software under Linux (and perhaps Windows). Actually, I would like to make a console-based software. I would like to know how could I manage entries from keyboards. I think that ncurses lib is a good choice. But my problem is in algorithm term. I think that making a code in the main() like this: while (true) { if (key is pressed) { switch (value of the key) { case 'A': proceed to FFT ; break; case 'B': proceed to time stretch break; case 'C: reduce volume break; ... ... } } wait for a certain time; } is not a good idea. I know that with MFC there is event management with WM messages. I don't know what is there under Linux, especially in console-based apps. With GUI libs like GTK, no problems I think. But what about console-based apps? Does anybody knows some internet sites, or some other libraries, or some methods (perhaps multithreads? seems to be heavy for just event managements...). I have look at ncurses docs but they shows an example with a kind of loop like the one I just talk about above. Any advice is welcome Bye.
