Using Channels
Channels are blocking
| Code Block |
|---|
package main
import (
"fmt"
"time"
)
func main(){
//make channel of type string
c := make(chan,string)
//run in background
go count("sheep", c)
//block until message is pushed to the channel
msg:= <- c
fmt.Println(msg)
}
func count(thing string, c chan string) {
for i:=0; i <= 5; i++ {
//send message on channel
c <- thing
time.Sleep(time.Millisecond * 500)
}
} |
In the above code, the program exits once the count routine returns a message on the channel.
