SDL2学习笔记-1

1. int main() 一定要写为 int main(int argc,char* argv[]) 的形式。

   c

   SDL_window* window
   
   SDL_Surface* surface
   
   SDL_Init(SDL_INIT_VIDEO) //如果出错返回-1
   
   SDL_GetError()
   
   window = SDL_CreateWindow("title",SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_SHOWN)
   
   surface = SDL_GetWindowSurface(window)
   
   SDL_Event e; //防止窗口关闭
   bool quit = false;
   while (quit == false) { 
   	while (SDL_PollEvent(&e)) {
   		if (e.type == SDL_QUIT) {
   			quit = true;
   		}
   	}
   }
