NAME
install_mouse - Installs the Allegro mouse handler.
SYNOPSIS
#include <allegro.h>
int install_mouse();
DESCRIPTION
Installs the Allegro mouse handler. You must do this before using any
other mouse functions.
RETURN VALUE
Returns -1 on failure, zero if the mouse handler is already installed
(in which case this function does nothing) and the number of buttons on
the mouse if the mouse handler has successfully been installed (ie.
this is the first time a handler is installed or you have removed the
previous one).
Note that the number of mouse buttons returned by this function is more
an indication than a physical reality. With most devices there is no
way of telling how many buttons there are, and any user can override
the number of mouse buttons returned by this function with a custom
configuration file and the variable num_buttons. Even if this value is
overridden by the user, the global mouse variables will still report
whatever the hardware is sending.
