swapinterval(3G) swapinterval(3G)
NAME
swapinterval - defines a minimum time between buffer swaps
SPECIFICATION
C swapinterval(i)
short i;
FORTRAN subroutine swapin(i)
integer*4 i
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 mode.
