SDL_Flip

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.
