使用 SDL2 跨平台多媒体开发库

SDL2 学习(1): 第一个程序

#include <SDL2/SDL.h>

int main(int argc, char *argv[]) {
    SDL_Window *Window = NULL;
    SDL_Renderer *Renderer = NULL;

    SDL_Init(SDL_INIT_VIDEO);

    Window = SDL_CreateWindow(
            "hello,word",
            SDL_WINDOWPOS_UNDEFINED,
            SDL_WINDOWPOS_UNDEFINED,
            800,
            600,
            SDL_WINDOW_RESIZABLE
    );

    Renderer = SDL_CreateRenderer(Window, -1, SDL_RENDERER_ACCELERATED);

    SDL_Event event;
    bool quit = false;

    while (!quit) {
        if (SDL_PollEvent(&event)) {
            if (event.type == SDL_QUIT) {
                quit = true;
            }
        }
        SDL_SetRenderDrawColor(Renderer, 0,180,180,255);
        SDL_RenderClear(Renderer);
        SDL_RenderPresent(Renderer);
    }
    SDL_DestroyRenderer(Renderer);
    SDL_DestroyWindow(Window);
    SDL_Quit();
    return 0;
}
