swapinterval − defines a minimum time between buffer swaps

SPECIFICATION

C
swapinterval(i)
short i;

FORTRAN
subroutine swapin(i)
integer*4 i

Pascal
procedure swapinterval(i: Short);

DESCRIPTION

swapinterval defines a minimum time between buffer swaps.  For example, a swap interval of 5 refreshes the screen at least five times between execution of successive swapbuffers.  swapinterval changes frames at a steady rate if a new image can be created within one swap interval.  The default interval is 1.  swapinterval is valid only in double buffer mode.  It is ignored in single buffer or RGB mode.
