NAME

       SDL_Flip - Swaps screen buffers

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.
