NAME
SDL_OpenHapticFromJoystick - Open a haptic device for use from a joystick device.
HEADER FILE
Defined in SDL3/SDL_haptic.h
SYNOPSIS
#include "SDL3/SDL.h" SDL_Haptic * SDL_OpenHapticFromJoystick(SDL_Joystick *joystick);

If not, on some implementations the haptic device will also get unallocated and you'll be unable to use force feedback on that device.
FUNCTION PARAMETERS
joystick the SDL_Joystick to create a haptic device from.
RETURN VALUE
( SDL_Haptic *) Returns a valid haptic device identifier on success or NULL on failure; call SDL_GetError () for more information.
