Query whether a gamepad has a given button.
SDL_bool SDL_GamepadHasButton(SDL_Gamepad *gamepad, SDL_GamepadButton button);
|button||a button enum value (an SDL_GamepadButton value)|
Returns SDL_TRUE if the gamepad has this button, SDL_FALSE otherwise.
This merely reports whether the gamepad's mapping defined this button, as that is all the information SDL has about the physical device.
This function is available since SDL 3.0.0.
