title: Golang: Kill an os.Process with exec.ExitError
body: <p>If I have a os.Exec object called "myCmd" and I call myCmd.Process.Kill(), what is the return code behavior of the process? Will it return a exec.ExitError? I want to forcefully kill the os.Exec process (i.eo kill -9), have it return a exec.ExitError or something that my goroutine can distinguish for a normal cmd exit with return code 0. </p>
  
  <p>What I have so far:</p>
  
  <pre><code>myCmd.Start()
  
  var cmdWatcher = func(childCmd os.Cmd) {
  
      err := childCmd.Wait()
      if exitErr, k := err.(*exec.ExitError); k {
          fmt.Print("ExitError detected")
      }
      return 
  }
  
  go cmdWatcher(myCmd)
  
  myCmd.Process.Kill()
  </code></pre>
