SDL_Flip(3)							 SDL API Reference						       SDL_Flip(3)

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 flip-
       ping.

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