swapinterval(3G)

NAME
     swapinterval - defines a minimum time between buffer swaps

C SPECIFICATION
     void swapinterval(i)
     short i;

PARAMETERS
     i   expects the number of retraces to wait before swapping the front and
         back buffers.  The default interval is 1.

DESCRIPTION
     swapinterval defines a minimum number of retraces between buffer swaps.
     For example, for a swap interval of 5, the system refreshes the screen at
     least five times between successive buffer swaps. swapinterval changes
     frames at a steady rate if a new image can be created within one swap
     interval.

     Like the swapbuffers and mswapbuffers commands that it affects,
     swapinterval is ignored by framebuffers in single buffer mode.

     A single swap interval counter is shared by the normal, overlay, and
     underlay framebuffers.  The interval is enforced between all buffer swap
     requests, regardless of which framebuffers are swapped.
