    Curses keyboard input without pause

    Actually, I'm programming in windows, but since Curses is a linux thing I figure i'd have more luck here. Of courses, if I'm wrong, moderators, feel free to move this message.

    Okay, I've made this tetris program and I'm trying to click with as few and as simple libraries as I can, so I don't want to load any others, and I'm tired of the TAP-TAP-TAPping to get the pieces into place. I'd prefer if when I depressed the key the left-right moved and when you released it stopped, with some reasonable delay so as to avoid on too-fast computers that far left and far right become the only options.

    I've been over the documenataion and I'm not sure it can be done. Am I wrong?

    I'm not sure why it's not already working. Do you have keyboard autorepeat disabled? In standard curses there is no way to get the key up/down state -- you get characters, not key motions. You will have to rely on the terminal (Windows command shell in this case?) to auto-repeat the keys for you. The problem would be the same on UNIX as well, if auto-repeat is off.

    The answer might be in your particular curses version for Windows. It might be turning off the auto-repeat for some reason. It might have some (nonstandard) function to turn it back on again.

    Maybe. What happens is you depress the key and after a brief pause it starts repeating. Maybe that is a windows thing.

    Is there no such thing as interrupts?

    No. Curses is fundamentally a terminal-based system. As such it has no way of representing such concepts as a "key press." All it knows is that it can read from the terminal, and write to it. Everything else is up to the terminal.
