Detailed description of my changes: SDL/configure.in: If Photon detected declare define ENABLE_PHOTON. SDL/src/video/SDL_sysvideo.h: Added extern to ph_bootstrap. SDL/src/video/SDL_video.c: Added ph_bootstrap to bootstrap array. SDL/src/video/photon/SDL_ph_events.c: Declare DISABLE_X11 if compiled for Photon. SDL/src/video/photon/SDL_ph_image.c: Fixed segment violation on exit. Please update BUGS file. SDL/src/video/photon/SDL_ph_video.c: 1. Enabling window manager. 2. Added to device capabilities Photon Window Manager functions: SetCaption and IconifyWindow. 3. Renamed X11_bootstrap to ph_bootstrap. 4. Removed SEGFAULT termination of programs if Photon not available. SDL/src/video/photon/SDL_ph_wm.c: 1. Declare DISABLE_X11 if compiled for Photon. 2. Added ph_SetCaption and ph_IconifyWindow code.

.TH "SDL_Flip" "3" "Mon 12 Mar 2001, 01:04" "SDL" "SDL API Reference" 
.SH "NAME"
SDL_Flip\- Swaps screen buffers
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBint \fBSDL_Flip\fP\fR(\fBSDL_Surface *screen\fR);
.SH "DESCRIPTION"
.PP
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 \fISDL_UpdateRect\fR\fB(screen, 0, 0, 0, 0)\fR
.PP
The \fBSDL_DOUBLEBUF\fP flag must have been passed to \fISDL_SetVideoMode\fR, when setting the video mode for this function to perform hardware flipping\&.
.SH "RETURN VALUE"
.PP
This function returns \fB0\fR if successful, or \fB-1\fR if there was an error\&.
.SH "SEE ALSO"
.PP
\fI\fBSDL_SetVideoMode\fP\fR, \fI\fBSDL_UpdateRect\fP\fR, \fI\fBSDL_Surface\fR\fR
