获取IP地址和MAC地址

先获取IP地址,再通过IP地址获取MAC地址,Mark一下.

//获得IP地址  
WSADATA wsaData;  
char name[155];  
char * ip;  
PHOSTENT hostinfo;  
if(WSAStartup(MAKEWORD(2,0),&wsaData)==0)  
{  
    if((gethostname(name,sizeof(name))==0))  
    {  
        if((hostinfo=gethostbyname(name))!=NULL)  
        {  
            ip=inet_ntoa(*(struct in_addr*)*hostinfo->h_addr_list);  
        }  
    }  
    WSACleanup();  
}  

//获得MAC地址  
HRESULT hr;  
IPAddr  ipAddr;    
ULONG   pulMac[2];    
ULONG  ulLen;    
ipAddr = inet_addr(ip);//设备自身的ip "192.168.201.183"    
memset (pulMac, 0xff, sizeof (pulMac));    
ulLen = 6;    
hr = SendARP (ipAddr, 0, pulMac, &ulLen);  
PBYTE pbHexMac = (PBYTE) pulMac;  
CString str=_T(""),str1;  
int i;  
for(i=0;i<ulLen;i++)  
{  
    str1.Format(_T("%02X "),pbHexMac[i]);  
    str+=str1;  
}

//获得IP地址

WSADATA wsaData;

char name[155];

char * ip;

PHOSTENT hostinfo;

if(WSAStartup(MAKEWORD(2,0),&wsaData)==0)

{

if((gethostname(name,sizeof(name))==0))

{

if((hostinfo=gethostbyname(name))!=NULL)

{

ip=inet_ntoa(*(struct in_addr*)*hostinfo->h_addr_list);

}

WSACleanup();

}

//获得MAC地址

HRESULT hr;

IPAddr ipAddr;

ULONG pulMac[2];

ULONG ulLen;

ipAddr = inet_addr(ip);//设备自身的ip "192.168.201.183"

memset (pulMac, 0xff, sizeof (pulMac));

ulLen = 6;

hr = SendARP (ipAddr, 0, pulMac, &ulLen);

PBYTE pbHexMac = (PBYTE) pulMac;

CString str=_T(""),str1;

int i;

for(i=0;i<ulLen;i++)

{

str1.Format(_T("%02X "),pbHexMac[i]);

str+=str1;

}
