load_joystick_data (3) - Linux Manuals

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

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.
