没有这样的文件返回err为零时如何使用os.Open

package main

import (
    "fmt"
    "os"
)

func main() {
    f := "D:\\cron"
    fmt.Println(os.Stat(f))
    fmt.Println(os.Open(f))

    f = "D:\\con"
    fmt.Println(os.Stat(f))
    fmt.Println(os.Open(f))
}

result：
<nil> CreateFile D:\cron: The system cannot find the file specified.
<nil> open D:\cron: The system cannot find the file specified.
<nil> CreateFile D:\con: The parameter is incorrect.
&{0xc000086a00} <nil>

I think when the file doesn't exist,os.Open should return err != nil
But I wonder why "D:\con" returns err == nil

Are you using Windows by any chance? "con" is a reserved file name, a relic of the DOS days.
