Golang determines whether the directory is empty

example:

package main

import (
    "fmt"
    "io/ioutil"
)

func main() {
    dirname := "/root/test"
    dir, _ := ioutil.ReadDir(dirname)
    if len(dir) == 0 {
        fmt.Println(dirname + " is empty dir!")
    } else {
        fmt.Println(dirname + " is not empty dir!")
    }
}
