[SDL] SDL_Flip question about buffer contents

[David Olsen]

Hi folks,
If I'm exclusively dealing with software surfaces, do I have any sort of guarantee as to what is in the video buffer after a call to SDL_Flip(screen)? Will what was just drawn to screen still be there, or will it be gone/changed on some platforms? I use windows exclusively for now, but I'd also like to try some Linux programming soon, and maybe MacOS, too. I know that hardware screen surfaces can be a variety of things after being SDL_Flipped due to various driver implementations, but what about software? Anyone know for sure?
Thanks,
-Dave Olsen
