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;}
