如题:
  我想在VC中实现获取本地主机的子网掩码和网卡类型,请问各位大虾,需要用到哪些函数,具体思路是怎么样的

    }

    }

    return 0 ;
}

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;

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;

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;

我也是一点一点搜的 也顺便学习一下
不知道是不是你要的

感谢cdmalcl,基本的解决思路我已经明白了,真的很感谢你的帮助.
