swapbuffers(3G) 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.
