typedef struct _IP_ADAPTER_INFO {
struct _IP_ADAPTER_INFO* Next;//链表指针域，通过这个来遍历静态键表
DWORD ComboIndex;//保留未用
char AdapterName[MAX_ADAPTER_NAME_LENGTH + 4];//网卡名
char Description[MAX_ADAPTER_DESCRIPTION_LENGTH + 4];//对网卡的描述
UINT AddressLength;//物理地址的长度，通过这个显示下面数组中的物理地址
BYTE Address[MAX_ADAPTER_ADDRESS_LENGTH];//物理地址，每个字节存放一个十六进制的数值，配合上一个数据域在printf中用x格式把每个字节输出。
DWORD Index;//网卡索引号
UINT Type;//网卡类型
UINT DhcpEnabled;//是否启用了DHCP动态IP分配
PIP_ADDR_STRING CurrentIpAddress;//当前使用的IP地址
IP_ADDR_STRING IpAddressList;//绑定到此网卡的IP地址链表，重要项目
IP_ADDR_STRING GatewayList;//网关地址链表，重要项目
IP_ADDR_STRING DhcpServer;//DHCP服务器地址，只有在DhcpEnabled==TRUE的情况下才有效
BOOL HaveWins;//是否启用了WINS
IP_ADDR_STRING PrimaryWinsServer;//主WINS地址
IP_ADDR_STRING SecondaryWinsServer;//辅WINS地址
time_t LeaseObtained;//当前DHCP租借获取的时间
time_t LeaseExpires;//当前DHCP租借失效时间。这两个数据结构只有在启用了DHCP时才有用。
} IP_ADAPTER_INFO, *PIP_ADAPTER_INFO;
----------------解决方案--------------------------------------------------------
IP_INTERFACE_INFO结构的解释如下：
typedef struct _IP_INTERFACE_INFO {
LONG NumAdapters;// 动态数组中网络接口元素的个数，通过它来遍历数组
IP_ADAPTER_INDEX_MAP Adapter[1];// 网络接口数据数组
} IP_INTERFACE_INFO,*PIP_INTERFACE_INFO;
其中的IP_ADAPTER_INDEX_MAP结构如下：
typedef struct _IP_ADAPTER_INDEX_MAP {
ULONG Index;// 网卡索引
WCHAR Name[MAX_ADAPTER_NAME];// 网卡名
} IP_ADAPTER_INDEX_MAP, * PIP_ADAPTER_INDEX_MAP;
----------------解决方案--------------------------------------------------------
typedef struct _IP_ADDR_STRING {
struct _IP_ADDR_STRING* Next;
IP_ADDRESS_STRING IpAddress;
IP_MASK_STRING IpMask; DWORD Context;
} IP_ADDR_STRING, *PIP_ADDR_STRING;
typedef struct {
char String[4 * 4];
} IP_ADDRESS_STRING, *PIP_ADDRESS_STRING, IP_MASK_STRING, *PIP_MASK_STRING;
