go - Golang: Kill an os.Process with exec.ExitError

Question

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.

What I have so far:

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()
