NAME

       gl_enablepageflipping - enables automatic page flipping

SYNOPSIS

       #include <vgagl.h>

       int gl_enablepageflipping(GraphicsContext *gc);

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.
