2 window, same content

SDL Development

Hi Everyone,

I would like to know to is there any way to mirror the content from one window to another.
Like clone the SDL_RENDER before calling SDL_RenderPresent

or Do I have to make 2 different SDL_RENDER and when I open an image I have to do it twice like this:
IMG_LoadTexture(RENDER1,“filename”)
IMG_LoadTexture(RENDER2,“filename”)

Thanks. KJ
