load_joystick_data - Loads joystick calibration data. Allegro game programming library.

       Restores  calibration  data  previously stored by save_joystick_data() or the setup utility. This sets up
       all aspects of the joystick code: you don't even need to call install_joystick() if you  are  using  this
       function. Pass a NULL filename to read the data from the currently selected configuration file.

       load_joystick_data - Loads joystick calibration data. Allegro game programming library.

       Returns  zero  on  success: if it fails the joystick state is undefined and you must reinitialise it from
       scratch.
