Date: Mon, 18 Feb 2002 16:46:59 +1200 From: Julian Kinraid <jkinraid@clear.net.nz> Subject: Patches for photon port of SDL Hi, A couple more patches for photon and the nto audio. Adds mouse grabbing support, fixed cursor images, unicode keyboard events (though no unicode data on kye release, is that a problem?), hopefully fixing some audio lag problems, and a few other fixes. Thanks, Julian Kinraid

>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
