poll_joystick(3)		 Allegro manual 		poll_joystick(3)

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).
