I'm trying to use a select
in a loop to receive either a message or a timeout signal. If the timeout signal is received, the loop should abort:
package main
import ("fmt"; "time")
func main() {
done := time.After(1*time.Millisecond)
numbers := make(chan int)
go func() {for n:=0;; {numbers <- n; n++}}()
for {
select {
case <-done:
break
case num := <- numbers:
fmt.Println(num)
}
}
}
However, it doesn't seem to be stopping:
$ go run a.go
0

[...]
Why? Am I using time.After
wrong?
