NAME

SDL_Flip- Swaps screen buffers

SYNOPSIS

#include

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.
