Simple Goroutines examples

goroutines.go

package main

import (
	"fmt"
	"time"
)

func longFunction(name string, dur time.Duration) {
	fmt.Printf("Started %s: lasting %s\n", name, dur)
	time.Sleep(dur)
	fmt.Printf("Finished %s\n", name)
}

func main() {
	go longFunction("long event", time.Duration(10*time.Second))
	go longFunction("medium event", time.Duration(6*time.Second))
	go longFunction("short event", time.Duration(3*time.Second))

	time.Sleep(12 * time.Second)
}

result

$ go run goroutines.go
Started long event: lasting 10s
Started medium event: lasting 6s
Started short event: lasting 3s
Finished  short event
Finished  medium event
