How to use SDL_OPENGLBLIT

Hi All,
Could someone point out to me in which situation I would use SDL_OPENGLBLIT and how to use it. I did not see any examples in the documentation.

Thanks,

Dominique

look at tesgl.c example in SDL distribution.

if you call it with “-logo” it use SDL_OPENGLBLIT …

what doeas means this flag anyway ?
it means that you want do ordinary (2D) blit operation on your opengl
frame buffer. (normally you could only successfully do glCall … in
OpenGL mode)

there is some special intern for this ! maybe it draw to a hidden
surface and blit it after, i don’t know, but this has performance drawback.
