NAME
       install_keyboard_hooks - Installs custom keyboard hooks. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void install_keyboard_hooks(int (*keypressed)(), int (*readkey)());

DESCRIPTION
       You  should only use this function if you *aren't* using the rest of the keyboard handler. It should be called in the place of install_key-
       board(), and lets you provide callback routines to detect and read keypresses, which will be used by the main  keypressed()  and  readkey()
       functions. This can be useful if you want to use Allegro's GUI code with a custom keyboard handler, as it provides a way for the GUI to get
       keyboard input from your own code, bypassing the normal Allegro input system.
