/**
 * \mainpage SDL_haptic
 *
 * The SDL Haptic subsystem allows you to control haptic (force feedback)
 *  devices.
 *
 * The basic usage is as follows:
 *   - Initialize the Subsystem (SDL_INIT_HAPTIC).
 *   - Open a Haptic Device.
 *     - SDL_HapticOpen(...) to open from index.
 *     - SDL_HapticOpenFromJoystick(...) to open from an existing joystick.
 *   - Create an effect (SDL_HapticEffect).
 *   - Upload the effect with SDL_HapticNewEffect(...).
 *   - Run the effect with SDL_HapticRunEffect(...).
 *   - (optional) Free the effect with SDL_HapticDestroyEffect(...).
 *   - Close the haptic device with SDL_HapticClose(...).
 *
 *
 * Example:
 *
 * \code
 * int test_haptic( SDL_Joystick * joystick ) {
 *    SDL_Haptic *haptic;
 *    SDL_HapticEffect effect;
 *    int effect_id;
 *
 *    // Open the device
 *    haptic = SDL_HapticOpenFromJoystick( joystick );
 *    if (haptic == NULL) return -1; // Most likely joystick isn't haptic
 *
 *    // See if it can do sine waves
 *    if ((SDL_HapticQueryEffects(haptic) & SDL_HAPTIC_SINE)==0) {
 *       SDL_HapticClose(haptic); // No sine effect
 *       return -1;
 *    }
 *
 *    // Create the effect
 *    memset( &effect, 0, sizeof(SDL_HapticEffect) ); // 0 is safe default
 *    effect.type = SDL_HAPTIC_SINE;
 *    effect.periodic.period = 1000; // 1000 ms
 *    effect.periodic.magnitude = 20000; // 20000/32767 strength
 *    effect.periodic.length = 5000; // 5 seconds long
 *    effect.periodic.attack_length = 1000; // Takes 1 second to get max strength
 *    effect.periodic.fade_length = 1000; // Takes 1 second to fade away
 *
 *    // Upload the effect
 *    effect_id = SDL_HapticNewEffect( haptic, &effect );
 *
 *    // Test the effect
 *    SDL_HapticRunEffect( haptic, effect_id );
 *    SDL_Delay( 5000); // Wait for the effect to finish
 *
 *    // We destroy the effect, although closing the device also does this
 *    SDL_HapticDestroyEffect( haptic, effect_id );
 *
 *    // Close the device
 *    SDL_HapticClose(haptic);
 *
 *    return 0; // Success
 * }
