gl_enablepageflipping (3)
enables automatic page flipping
SYNOPSIS
DESCRIPTION
Enable page flipping or triple buffering in
gl_copyscreen (3)
if the physical context
gc
can do it.
Returns 3 if triple
buffering will be used, 2 for page flipping, 0 if page
flipping is not possible (due to video memory/mode
limitations).
When pageflipping is enabled, the
gl_screenoffset (3)
is ignored in
gl_copyscreen (3).
The idea is that you draw your picture in
gc
and copy it to the screen by consecutive
gl_copyscreen (3)
calls. Each of these will choose a free buffer in the screen and
adjust the display start accourdingly.
The current context must by the VGA when
gl_copyscreen (3)
is called in this situation.
