install_keyboard_hooks - Installs custom keyboard hooks. Allegro game
programming library.
#include <allegro.h>
void install_keyboard_hooks(int (*keypressed)(), int
(*readkey)());
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_keyboard(), 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.
