Golang - concurrency 之 Goroutines

 

A goroutine is a function that is capable of running concurrently with other functions. To create a goroutine we use the keyword go followed by a function invocation:

 

 

package main

import "fmt"

func f(n int) {
  for i := 0; i < 10; i++ {
    fmt.Println(n, ":", i)
  }
}

func main() {
  go f(0)
  var input string
  fmt.Scanln(&input)
}

　　结果：

 

  0 : 0
  0 : 1

　多次运行的结果

   0 : 0
  0 : 1
  0 : 2
  0 : 3
  0 : 4
  0 : 5
  0 : 6
