Code Examples

#include <SDL3/SDL.h>

int main(int argc, char *argv[])
{
    SDL_Window *window;
    SDL_Renderer *renderer;
    SDL_Surface *surface;
    SDL_Texture *texture;
    SDL_Event event;

    if (!SDL_Init(SDL_INIT_VIDEO)) {
        SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't initialize SDL: %s", SDL_GetError());
        return 3;
    }

    if (!SDL_CreateWindowAndRenderer("Hello SDL", 320, 240, SDL_WINDOW_RESIZABLE, &window, &renderer)) {
        SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't create window and renderer: %s", SDL_GetError());
        return 3;
    }

    surface = SDL_LoadBMP("sample.bmp");

        SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't create surface from image: %s", SDL_GetError());
        return 3;
    }
    texture = SDL_CreateTextureFromSurface(renderer, surface);
    if (!texture) {
        SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't create texture from surface: %s", SDL_GetError());
        return 3;
    }
    SDL_DestroySurface(surface);

    while (1) {
        SDL_PollEvent(&event);
        if (event.type == SDL_EVENT_QUIT) {
            break;
        }
        SDL_SetRenderDrawColor(renderer, 0x00, 0x00, 0x00, 0x00);
        SDL_RenderClear(renderer);
        SDL_RenderTexture(renderer, texture, NULL, NULL);
        SDL_RenderPresent(renderer);
    }

    SDL_DestroyTexture(texture);
    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);

    SDL_Quit();
