NAME [Toc]

 doublebuffer - sets the display mode to double buffer mode

C SPECIFICATION [Toc]

 void doublebuffer()

PARAMETERS [Toc]

 none

DESCRIPTION [Toc]

 doublebuffer sets the display mode	to double buffer mode.	It does	not
 take effect until gconfig is called. In double buffer mode, the
 bitplanes are partitioned into two	groups,	the front bitplanes and	the
 back bitplanes. Double buffer mode displays only the front bitplanes.
 Drawing routines normally update only the back bitplanes; frontbuffer and
 backbuffer	can override the default.
 In	double buffer mode, gconfig calls frontbuffer(OFF) and backbuffer(ON).

SEE ALSO [Toc]

 backbuffer, frontbuffer, gconfig, getbuffer, getdisplaymode, RGBmode,
 singlebuffer, swapbuffers

NOTE [Toc]

 This routine is available only in immediate mode.
