how do i stop/exit a coroutine?

[system]

how can i stop or exit function while its working?
my code is below

function ChangeColor(){
   timer = 0;
   RandomNumber=Random.Range(5,9);
   yield WaitForSeconds(RandomNumber);
   renderer.material.SetTexture("_MainTex", yellow);
   cc=1;
}

i want to stop this function or change “waitforseconds” time while the program waiting for “randomnumber”.
for some reason, i just wanna let it finish running this function as soon as possible.

any help would be appreciated

This is not exactly a function, it’s a coroutine. To exit them while they are being run you can use MonoBehaviour.StopCoroutine();
