What does /dev/stdin mean in windows?

Question

go

The code looks like this:

func main(){
...
filesWithMatch += countLines(os.Stdin, counts)
...
}

func countLines(f *os.File, counts map[string]int) string {
  input := bufio.NewScanner(f)
  for input.Scan() {
    counts[input.Text()]++
  }
  for _, n := range counts {
    if n > 1 {
      return f.Name()
    }
  }
  return ""
}

If you pass stdin as arguments and not a file, then /dev/stdin will be written to filesWithMatch. Is it correct to assume that the input stream is some kind of file or not?

Answer 1

Apparently the same as in Libux/FreeBSD: a file associated with "standard input". Tell more?

Answer 2

stdin can be either a file or just a stream, the output of another program.
