     3 SDL_Flip \- Swaps screen buffers

     4 .SH "SYNOPSIS"

     5 .PP

     6 \fB#include "SDL\&.h"

     7 .sp

     8 \fBint \fBSDL_Flip\fP\fR(\fBSDL_Surface *screen\fR);

     9 .SH "DESCRIPTION"

    10 .PP

    11 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 \fISDL_UpdateRect\fR\fB(screen, 0, 0, 0, 0)\fR

    12 .PP

    13 The \fBSDL_DOUBLEBUF\fP flag must have been passed to \fISDL_SetVideoMode\fR, when setting the video mode for this function to perform hardware flipping\&.

    14 .SH "RETURN VALUE"

    15 .PP

    16 This function returns \fB0\fR if successful, or \fB-1\fR if there was an error\&.
