求一个 linux 下使用 SDL_ttf 显示文字的demo

[哈撒keyi]

如题，实在是找了好久，都没找到好的例子。自己对照写的也莫名奇妙的退出了

这是我写的代码（功能是弹出一个窗口，上面显示注意休息）懂得老哥帮忙看下，能写个demo更好了：

void rest_remander(void){

        //初始化SDL
        SDL_Surface *screen;
        Uint32 color;

        if(SDL_Init(SDL_INIT_VIDEO)<0){
                //fprintf(stderr,"无法初始化SDL:%s\n",SDL_GetError);
                //exit(1);
                writeLog("无法初始化SDL");
                return;

        }
        screen = SDL_SetVideoMode(640,480,16,SDL_SWSURFACE);
        if(screen==NULL){
                //fprintf(stderr,"无法设置640*480，16位色的视频模式：%s\n",SDL_GetError);
//exit(1);
                writeLog("无法设置视频模式");
                return;
        }
        atexit(SDL_Quit);

        //初始化TTF库
        if( TTF_Init() == -1){
                writeLog("初始化TTF库失败");
                return -1;
        }
        //创建一个对应某字体文件的TTF_Font
        TTF_Font *font;
        font = TTF_OpenFont("/usr/local/share/fonts/simfang.ttf",16);
        if(!font){
                printf("TTF_OpenFont:Open /usr/local/share/fonts/simfang.ttf %s\n", TTF_GetError());
                writeLog("创建字体失败");
                return -1;
        }
        //设置字体颜色
        SDL_Color textColor = {255, 255, 255};
SDL_Surface * message;
        message = TTF_RenderText_Solid( font, "注意休息", textColor);
        if(message){
                apply_surface(0,0,message,screen);
        }
        //刷新屏幕
        if(SDL_Flip(screen) == -1){
                writeLog("刷新屏幕失败");
                return -2;
        }
        SDL_Delay(2000);

        SDL_FreeSurface(message);

        //释放字体
        TTF_CloseFont( font );
        TTF_Quit();
        return ;
}
void apply_surface( int x, int y, SDL_Surface* source, SDL_Surface* destination ){
        //Temporary rectangle to hold the offsets
        SDL_Rect offset;
        //Get the offsets
        offset.x = x;
        offset.y = y;
        //Blit the surface
        SDL_BlitSurface( source, NULL, destination, &offset );
}

里面的writeLog（）作用是写日志
