load_joystick_data - Man Page

#include <allegro.h>

int load_joystick_data(const char *filename);

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.

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