In Go
I can write such code for creating a gorouting that sleeps 5
sec.
func sleep(link chan interface{}){
time.Sleep(5 * time.Second)
fmt.Println("I've slept for 5 sec")
link <- struct {}{}
}
func main() {
var link = make(chan interface{})
go sleep(link)
time.Sleep(1 * time.Second)
// here I want to change the remaining sleeping time of `sleep` goroutine to 0.5 sec
<- link
}
What if in main
function I change my mind and decide that the sleeper should sleep not 5
sec but 3
. How can it done if goroutine already started to sleep (and sleeping, for example, for 1
sec)?
UPDATE
I mean is there something whereby I can manage that unique goroutine while it sleeps. Like giving commands to it about decreasing or increasing time of sleep:
func main() {
// ...
time.Sleep(1)
something.ManageRemainingTime(10)
time.Sleep(5)
something.ManageRemainingTime(100)
time.Sleep(8)
something.ManageRemainingTime(0.5)
// ...
}
