poll_joystick3alleg4

Usage

Overview

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).
