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).
