In the if, the SDL_Init(SDL_INIT_EVERYTHING) part will return 0, which evaluates to false but it still means that SDL was successfully initialized. The ! in front, means the entire if will evaluate to true, and -1 will be returned. Solution. A better soltion is to check if it's equal to 0 and if it does fail, used SDL_GetError() to print the error.

Thank you human! (Ubuntu 20.04 LTS)
