|
.PP
|
||
|
|
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
|

|
.PP
|
||
|
|
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\&.

.SH "RETURN VALUE"
|
||
|
|
.PP
|
||
|
|
This function returns \fB0\fR if successful, or \fB-1\fR if there was an error\&.
