Get the implementation-dependent path for an opened game controller.
const char* SDL_GameControllerPath(SDL_GameController *gamecontroller);
a game controller identifier previously returned by SDL_GameControllerOpen()
Returns the implementation dependent path for the game controller, or NULL if there is no path or the identifier passed is invalid.
This is the same path as returned by SDL_GameControllerNameForIndex(), but it takes a controller identifier instead of the (unstable) device index.
This function is available since SDL 3.0.0.
