MAC地址在机器上 /过滤插头和播放设备的MAC地址

Question

我具有以下代码，该代码可以通过Windows Machine上的最多3个WiFi和Ethernet Adapter MAC地址填充字符数组：

IP_ADAPTER_INFO *info = NULL, *pos;
DWORD size = 0;
if (GetAdaptersInfo(info, &size) != ERROR_BUFFER_OVERFLOW)
    return;
info = (IP_ADAPTER_INFO *)malloc(size);
if (GetAdaptersInfo(info, &size) != ERROR_SUCCESS)
    return;
char addresses[1024];
char buffer[1024];
memset(addresses, 0, sizeof(addresses));
memset(buffer, 0, sizeof(buffer));
int recordedAddresses = 0;
for (pos = info; pos != NULL; pos = pos->Next) {
    if (pos->Type != IF_TYPE_IEEE80211 && pos->Type != MIB_IF_TYPE_ETHERNET)
        continue;
    if (recordedAddresses > 0)
        strcat_s<sizeof(addresses)>(addresses, " ");
    for (int i = 0; i < pos->AddressLength; i++) {
        sprintf_s<sizeof(buffer)>(buffer, i == 0 ? "%2.2x" : ":%2.2x", pos->Address[i]);
        strcat_s<sizeof(addresses)>(addresses, buffer);
    }
    recordedAddresses++;
    if (recordedAddresses >= 3)
        break;
}
free(info);
// The array called 'addresses' now contains something like this: a0:b1:c2:d3:e4:f5 0a:1b:2c:3d:4e:5f 00:01:02:03:04:05

如何检测这些IP_ADAPTER_INFO结构中的任何一个是指插入设备？有这样做的标准方式吗？我一直在寻找解决方案。理想情况下，我希望从我的addresses列表中过滤插件的WiFi加密狗，即具有USB接口的加密狗的类型，并允许您通过USB Dongle在Windows机器上运行WiFi连接(如果可能的话(。

您需要使用ip_adapter_addresses而不是ip_adapter_info struct。

专门寻找物理媒介，并通过地址交叉。
