15 Wherever possible, Allegro will read the mouse input asynchronously
16 (ie. from inside an interrupt handler), but on some platforms that may
17 not be possible, in which case you must call this routine at regular
18 intervals to update the mouse state variables. To help you test your
19 mouse polling code even if you are programming on a platform that
20 doesn't require it, after the first time that you call this function
21 Allegro will switch into polling mode, so from that point onwards you
22 will have to call this routine in order to get any mouse input at all,
23 regardless of whether the current driver actually needs to be polled or
24 not.

27 Returns zero on success, or a negative number on failure (ie. no mouse
28 driver installed).
