>Description</H2
><P
>On hardware that supports double-buffering, this function sets up a flip
and returns. The hardware will wait for vertical retrace, and then swap
video buffers before the next video surface blit or lock will return.
On hardware that doesn't support double-buffering, this is equivalent
to calling <A
HREF="sdlupdaterect.html"
>SDL_UpdateRect</A
><TT
CLASS="PARAMETER"
><I
>(screen, 0, 0, 0, 0)</I
></TT
></P
><P
>The <TT
CLASS="LITERAL"
>SDL_DOUBLEBUF</TT
> flag must have been passed to
<A
HREF="sdlsetvideomode.html"
>SDL_SetVideoMode</A
>,
when
setting the video mode for this function to perform hardware flipping.</P
