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
flipping.

RETURN VALUE

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