load_joystick_data(3alleg4)					  Allegro manual				       load_joystick_data(3alleg4)

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

SYNOPSIS
       #include <allegro.h>

       int load_joystick_data(const char *filename);

DESCRIPTION
       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.

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