Get the underlying joystick from a gamepad
SDL_Joystick* SDL_GetGamepadJoystick(SDL_Gamepad *gamepad);
|the gamepad object that you want to get a joystick from
Returns an SDL_Joystick object; call SDL_GetError() for more information.
This function will give you a SDL_Joystick object, which allows you to use the SDL_Joystick functions with a SDL_Gamepad object. This would be useful for getting a joystick's position at any given time, even if it hasn't moved (moving it would produce an event, which would have the axis' value).
The pointer returned is owned by the SDL_Gamepad. You should not call SDL_CloseJoystick() on it, for example, since doing so will likely cause SDL to crash.
This function is available since SDL 3.0.0.
