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).
