Module Termbox

module Termbox: sig .. end
Minimalistic API for creating text-based interfaces. Alternative to ncurses.

For API documentation see termbox.h.

One important difference is that values of TB_KEY_* that are in the ASCII range (< 256) are reported as Ascii and not Key.

So if you wanted to check for Ctrl + C you'd do something like this: 

    match Termbox.poll_event () with
    | Ascii c when c = '\x03' (* CTRL_C *) -> ...
