I was curious about the portability of some of the standard headers. For example, I know that <windows.h> is for machines running windows, but what about conio and conio2? I understand that they are not protable but what OSs will they run under. I was also curious about PDcurses. I have downloaded the dev pak but I have not been able to find much on documentation so I am unscertain about the functins available with it and how to use them. Can PDcurses run under any OS?
