结构体信息

The IP_ADAPTER_INFO structure contains information about a particular network adapter on the local computer.

结构体IP_ADAPTER_INFO包含本地计算机某一个网络适配器的信息。

定义

typedef struct _IP_ADAPTER_INFO {

struct _IP_ADAPTER_INFO* Next;//指向链表中下一个适配器信息的指针

DWORD ComboIndex;//预留值

char AdapterName[MAX_ADAPTER_NAME_LENGTH + 4];//使用ANSI字符串表示的适配器名称

char Description[MAX_ADAPTER_DESCRIPTION_LENGTH + 4];//使用ANSI字符串表示的适配器描述

UINT AddressLength;//适配器硬件地址以字节计算的长度

BYTE Address[MAX_ADAPTER_ADDRESS_LENGTH];//硬件地址以BYTE数组所表示

DWORD Index;//适配器索引

UINT Type;//适配器类型

UINT DhcpEnabled;//指定这个适配器是否开启DHCP

PIP_ADDR_STRING CurrentIpAddress;//预留值

IP_ADDR_STRING IpAddressList;//该适配器的IPv4地址链表

IP_ADDR_STRING GatewayList;//该适配器的网关IPv4地址链表

IP_ADDR_STRING DhcpServer;//该适配器的DHCP服务器的IPv4 地址链表

BOOL HaveWins;

IP_ADDR_STRING PrimaryWinsServer;

IP_ADDR_STRING SecondaryWinsServer;

time_t LeaseObtained;

time_t LeaseExpires;

} IP_ADAPTER_INFO,

*PIP_ADAPTER_INFO;

使用

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.

结构体ADAPTER_INFO只限制于获取本地计算机网络适配器的IPv4信息，该结构体通过调用GetAdaptersInfo函数获取值。

示例代码

// It is possible for an adapter to have multiple

// IPv4 addresses, gateways, and secondary WINS servers

// assigned to the adapter.

// Note that this sample code only prints out the

// first entry for the IP address/mask, gateway,

// and secondary WINS server for each adapter.

PIP_ADAPTER_INFO pAdapterInfo;

PIP_ADAPTER_INFO pAdapter = NULL;

DWORD dwRetVal = 0;

pAdapterInfo = (IP_ADAPTER_INFO *) malloc( sizeof(IP_ADAPTER_INFO) );

ulOutBufLen = sizeof(IP_ADAPTER_INFO);

// Make an initial call to GetAdaptersInfo to get

// the necessary size into the ulOutBufLen variable

if (GetAdaptersInfo( pAdapterInfo, &ulOutBufLen) != ERROR_SUCCESS) {

GlobalFree (pAdapterInfo);

pAdapterInfo = (IP_ADAPTER_INFO *) malloc (ulOutBufLen);

}

if ((dwRetVal = GetAdaptersInfo( pAdapterInfo, &ulOutBufLen)) == NO_ERROR) {

pAdapter = pAdapterInfo;

while (pAdapter) {

printf("\\tAdapter Name: \\t%s\", pAdapter->AdapterName);

printf("\\tAdapter Desc: \\t%s\", pAdapter->Description);

printf("\\tAdapter Addr: \\t");

for (UINT i = 0; i < pAdapter->AddressLength; i++)

printf("%x%c", pAdapter->Address[i],

i == pAdapter->AddressLength - 1 ? '\' : '-');

printf("\\tIP Address: \\t%s\", pAdapter->IpAddressList.IpAddress.String);

printf("\\tIP Mask: \\t%s\", pAdapter->IpAddressList.IpMask.String);

printf("\\tGateway: \\t%s\", pAdapter->GatewayList.IpAddress.String);

printf("\\t***\");

if (pAdapter->DhcpEnabled) {

printf("\\tDHCP Enabled: Yes\");

printf("\\t\\tDHCP Server: \\t%s\", pAdapter->DhcpServer.IpAddress.String);

printf("\\tLease Obtained: %ld\", pAdapter->LeaseObtained);

}

else

printf("\\tDHCP Enabled: No\");

if (pAdapter->HaveWins) {

printf("\\tHave Wins: Yes\");

printf("\\t\\tPrimary Wins Server: \\t%s\", pAdapter->PrimaryWinsServer.IpAddress.String);

printf("\\t\\tSecondary Wins Server: \\t%s\", pAdapter->SecondaryWinsServer.IpAddress.String);

}

else

printf("\\tHave Wins: No\");

pAdapter = pAdapter->Next;

}

}

else {

printf("Call to GetAdaptersInfo failed.\");
