sdl2pp - A modern C++20 wrapper around SDL2

Comparison between using the SDL2 API vs the SDL2++ API

SDL2

int main(int, char**) {
    if (SDL_Init(SDL_INIT_EVERYTHING) != 0)
        return EXIT_FAILURE;
    
    auto win = SDL_CreateWindow("Hello SDL2", 
                    SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,
                    800, 600,
                    SDL_WINDOW_RESIZABLE);
    if (win == nullptr)
        return EXIT_FAILURE;
    
    auto ren = SDL_CreateRenderer(win, -1, SDL_RENDERER_ACCELERATED);
    if (ren == nullptr)
        return EXIT_FAILURE;
    SDL_SetRenderDrawColor(ren, 255, 0, 0, 255);
    
    bool quit = false;
    while(!quit) {
        SDL_Event e;
        while(SDL_PollEvent(&e)) {
            if (e.type == SDL_QUIT)
                quit = true;
        }
        SDL_RenderClear(ren);
        SDL_RenderPresent(ren);
    }

    SDL_DestroyRenderer(ren);
    SDL_DestroyWindow(win);
    SDL_Quit();
}
