通过适配器描述更改Mac地址

我正在使用 Nate True @ 提供的优秀工具http://devices.natetrue.com/macshift/ http://devices.natetrue.com/macshift/它通过适配器名称更改 Mac 地址。这是源代码：

const int versionMinor = 1;

  return 0;
  }

除了名称之外，我还想通过适配器的描述来更改 Mac 地址。所以我需要修改这段代码，以便如果找不到匹配的名称，它会根据描述回退到更改 mac。

这是一个适配器示例：

名称： 本地连接

描述：Marvell Yukon 88E8055 PCI-E 千兆以太网控制器

不幸的是，作为一名 Java 开发人员，我对 C++ 的经验有限，因此我们将不胜感激。

下面是 GetAdaptersInfo 的 C 示例，它打印出每个适配器的名称和描述（您可以通过在匹配时调用 SetMAC 轻松地使其适合您的代码）：

    VOID EnumerateNetworkAdapters(VOID)
    {
        ULONG len = 0;
        if (ERROR_BUFFER_OVERFLOW == GetAdaptersInfo(NULL, &len;))
        {
            IP_ADAPTER_INFO *ipai;
            ipai = malloc(len);
            if (NO_ERROR == GetAdaptersInfo(ipai, &len;))
            {
                IP_ADAPTER_INFO *p = ipai;
                do
                {
                    printf("name=%s description=%s\n", p->AdapterName, p->Description);
                }
                while (p = p->Next);
            }
            free(ipai);
        }
    }
