poll_mouse(3)                   Allegro manual                   poll_mouse(3)



NAME
       poll_mouse - Polls the mouse. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>


       int poll_mouse();

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

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