SYNOPSIS

       #include "SDL.h"

       int SDL_Flip(SDL_Surface *screen);

DESCRIPTION

       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 SDL_UpdateRect(screen, 0, 0, 0, 0)

       The  SDL_DOUBLEBUF flag must have been passed to SDL_SetVideoMode, when
       setting the video mode for this function to perform hardware  flipping.

RETURN VALUE

       This function returns 0 if successful, or -1 if there was an error.
