Date: Thu, 13 Sep 2001 14:14:42 -0400 From: "David Chait" <davebytes@hotmail.com> Subject: sdlmods.zip -- Message: 502 -- Next: 503 N -------------------------------------------- now bracketed with (MWERKS && macintosh), so it'll work under metrowerks under any kind of mac build. Project Builder probably uses pack properly as it is GCC under the covers, so not worrying about it... :) it sets packing to 68K 4-byte alignment, and turns on enumsalwaysint. resets them both to project defaults when done. note that if a project sets these things in a header and expects the settings to last throughout a C file (which is a nasty thing to do), it won't work. I think there's an overall-state push/pop system, but it's a deprecated interface so I'm loathe to use it...

>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
