示例1: walkKey

func walkKey(t *testing.T, k registry.Key, kname string) {
	names, err := k.ReadValueNames(-1)
	if err != nil {
		t.Fatalf("reading value names of %s failed: %v", kname, err)
	}
	for _, name := range names {
		_, valtype, err := k.GetValue(name, nil)
		if err != nil {
			t.Fatalf("reading value type of %s of %s failed: %v", name, kname, err)
		}
		switch valtype {
		case registry.NONE:
		case registry.SZ:
			_, _, err := k.GetStringValue(name)
			if err != nil {
				t.Error(err)
			}
		case registry.EXPAND_SZ:
			s, _, err := k.GetStringValue(name)
			if err != nil {
				t.Error(err)
			}
			_, err = registry.ExpandString(s)
			if err != nil {
				t.Error(err)

			// TODO: not implemented
		default:

	}

					// ignore error, if we are not allowed to access this key
					return
				}
