swapbuffers(3G)

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

C SPECIFICATION
     void swapbuffers()

PARAMETERS
     none

DESCRIPTION
     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.
