load_joystick_data (3) Linux Manual Page

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.
