Linux analog to windows GetAsyncKeyState()

Question

Is there some Linux analog of windows function GetAsyncKeyState() ? Or maybe there exists some asynchronous function which returns - Does keyboard buffer empty or not ?

Thanks.

Answer 1

The key question here is: For which abstraction? X windows, ncurses or stdio? Linux isn't as simple and monolithic as Windows is.

For stdio (plain old stdin/stdout text program) fgetc_unlocked does the trick.
