Dbl buffering

SDL Development

Hi,

I'm new to SDL and have a question about dbl buffering. Can i assume that

after a SDL_Flip(Screen) call, the Screen surface will contain the graphics
just show, or could it in some configurations be fx. a blank surface?

I’m not sure about a fully software-based SDL implementation, but the
underlying hardware APIs generally do not guarantee that the back-buffer
contents are defined after a buffer swap. It would be best not to make any
assumptions about back-buffer contents after a swap (or flip…).
