What's the SDL-2.0 corresponding function for 'SDL_JoystickOpened'?

I tried to use SDL_JoystickOpened() in a SDL-2.0 code, but I got the error message SDL_JoystickOpened was not declared in this scope.

I've searched and found that SDL_JoystickOpened() no longer exists in SDL-2.0, but I didn't find the function that replaced it. Can anyone please tell me how can I replace SDL_JoystickOpened() in this piece of code:

SDL_Joystick *joy = SDL_JoystickOpen(0);
if (SDL_JoystickOpened(0) == 1)
{
    // do something
}

Thanks.

Solution

  • The documentation says the SDL_JoystickOpen() call returns a NULL pointer if it fails so just do a check for that:

    SDL_Joystick *joy = SDL_JoystickOpen(0);
if (joy) {
    // joy is a valid pointer so do stuff
}
