Simple use:

var nss = []string{"net"}

func main() {
	runtime.LockOSThread()
	defer runtime.UnlockOSThread()
	err := namespace.NewWrapper(nss, func() {
		//Do something
	})
	if err != nil {
		log.Fatal(err)
	}
}

• FromPid - return namespace from pid

• FromThread - return namespace from tid

• NewNetNamed - create named net namespace

• RemoveNetNamed - delete named net namespace

• NetFromName - return named net namespace

• NewWrapper - create new namespace, call function and return current ns

• Wrapper - call function and return current ns
