sdl2pp - A modern C++20 wrapper around SDL2

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

SDL2

intmain(int, char**) {
if (SDL_Init(SDL_INIT_EVERYTHING) != 0)
returnEXIT_FAILURE;
auto win = SDL_CreateWindow("Hello SDL2", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,
800, 600,
SDL_WINDOW_RESIZABLE);
if (win == nullptr)
returnEXIT_FAILURE;
auto ren = SDL_CreateRenderer(win, -1, SDL_RENDERER_ACCELERATED);
if (ren == nullptr)
returnEXIT_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();
}
