NAME

       poll_joystick - Polls the joystick. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int poll_joystick();

DESCRIPTION

       The  joystick  handler  is not interrupt driven, so you need to call this function every now and again to
       update the global position values. Example:

          do {
             /* Get joystick input */
             poll_joystick();

             /* Process input for the first joystick */
             if (joy[0].button[0].b)
                first_button_pressed();

             if (joy[0].button[1].b)
                second_button_pressed();
             ...
          } while(!done);

RETURN VALUE

       Returns zero on success or a  negative  number  on  failure  (usually  because  no  joystick  driver  was
       installed).
