結構體信息
The IP_ADAPTER_INFO structure contains information about a particular network adapter on the local computer.

ADAPTER_INFO structure is limited to IPv4 information about a particular network adapter on the local computer. The IP_ADAPTER_INFO structure is retrieved by calling the GetAdaptersInfo function.
結構體ADAPTER_INFO只限制於獲取本地計算機網路適配器的IPv4信息，該結構體通過調用GetAdaptersInfo函式獲取值。
其中，適配器類型Type欄位定義了已獲支持的適配器類型如下：
常數 | 數值 | 說明 |
MIB_IF_TYPE_ETHERNET | 6 | 乙太網適配器 |
MIB_IF_TYPE_FDDI | 15 | FDDI（光纖分布數據接口）適配器 |
MIB_IF_TYPE_LOOPBACK | 24 | Loopback適配器 |
MIB_IF_TYPE_OTHER | 1 | 其他類型的適配器 |
MIB_IF_TYPE_PPP | 23 | PPP適配器 |
MIB_IF_TYPE_SLIP | 28 | Slip適配器 |
MIB_IF_TYPE_TOKENRING | 9 | 令牌環適配器 |
