gl_enablepageflipping(3)      Svgalib User Manual     gl_enablepageflipping(3)

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.
