But now I have a further question: is it possible to implement generic callbacks in Gambas? I mean - many libraries have functions where you specify a callback to be called, like the glib function g_signal_connect(); it would be nice to implement them, even partly, without resorting to write a gambas component. May be that by using libffi it is possible to implement them fully, but even a simple event could do. My problem now is that using ALSA, I must poll continuously to see if some event is coming in, wasting a lot of CPU and losing precision. With a callback if would be much simpler...
I hope I have been clear enough.
