Ultimately, there is no such thing. For starters, the world of portable C includes platforms that don't even have a "keyboard" for starters, much less a "screen" keypresses would usually be echoed to. Keep in mind that there *might* be C programs running both _inside_ your mouse and _inside_ your keyboard. Your toaster might be controlled by a C program, and your microwave and washing machine rather probably are, these days. About the most portable way available to simulate a getch() would be to use a 'curses' library, like ncurses or pdcurses. Curses will hide the unportable aspect from your own program. -- Hans-Bernhard Broeker (broeker AT physik DOT rwth-aachen DOT de) Even if all the snow were burnt, ashes would remain.
