Oracle service failover后自动切回原来的node

一.SDL的下载

下载链接

二.SDL的环境配置

解压以后放在中文路径下

下面进行编译器的配置

x64\SDL2main.lib
x64\SDL2.lib

将这段代码放进去运行一下

#include <SDL.h>

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

    SDL_Init(SDL_INIT_VIDEO);

    window = SDL_CreateWindow("SDL Example", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 800, 600, 0);
    renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);

    SDL_SetRenderDrawColor(renderer, 255, 0, 0, 255); // 设置绘制颜色为红色
    SDL_RenderClear(renderer); // 清空渲染器
    SDL_RenderPresent(renderer); // 将绘制的内容显示到窗口上

    SDL_Delay(3000); // 等待3秒

    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);

    SDL_Quit();

    return 0;
}

这样就是成功了！！！
