SYNOPSIS

C
blink(rate, color, red, green, blue)
short rate;
Colorindex color;
RGBvalue red, green, blue;

FORTRAN
subroutine blink(rate, color, red, green, blue)
integer*2 rate, color, red, green, blue

Pascal
procedure blink(rate: Short; color: Colorindex; red, green, blue: RGBvalue);

DESCRIPTION

Blink specifies a blink rate, a color map index, and red, green, and blue values.  Every rate vertical retraces, the color located at index color in the current colormap is updated.  Its value is either the original value or the new value supplied by the red, green, and blue arguments. 

Up to twenty colors can blink simultaneously, each at a different rate.  The blink rate can be changed by calling blink again with the same color and a different rate.  Calling blink with rate=0 when color specifies a blinking colormap entry terminates the blinking and restores the original color.
