NAME    [Toc]    [Back]

     swapbuffers - exchanges the front and back	buffers	of the normal
     framebuffer

C SPECIFICATION    [Toc]    [Back]

PARAMETERS    [Toc]    [Back]

     none

DESCRIPTION    [Toc]    [Back]

     swapbuffers causes	the front and back buffers of the normal framebuffer
     to	be exchanged during the	next vertical retrace period.  Once an image
     is	fully drawn in the back	buffer,	swapbuffers displays it.  swapbuffers
     is	ignored	when the normal	framebuffer is in single buffer	mode.  It has
     no	effect on the overlay, underlay, or popup framebuffers,	regardless of
     the current draw mode.

     To	swap overlay or	underlay buffers, or to	swap buffers in	more than one
     framebuffer simultaneously, you must use mswapbuffers.
