SDL环境初始化测试代码

#include <SDL2/SDL.h>
int main()
{
    SDL_Window *window=NULL;
    SDL_Renderer *render=NULL;
    //初始化环境
    SDL_Init(0);
    //创建一个窗口
    window = SDL_CreateWindow("test",200,200,900,600,SDL_WINDOW_SHOWN|SDL_WINDOW_BORDERLESS);
    if(!window)
    {

    }
    //创建一个渲染器
    render = SDL_CreateRenderer(window,-1,0);
    if(!render)
    {
    }
    //设置背景色
    SDL_SetRenderDrawColor(render,255,0,0,30);
    SDL_RenderDrawLine(render,300,300,600,600);
    SDL_RenderClear(render);
    SDL_RenderPresent(render);
    SDL_Delay(5000);
    //删除渲染器
    SDL_DestroyRenderer(render);
    //删除窗口
    SDL_DestroyWindow(window);
    //卸载环境
    SDL_Quit();
    return 0;
