MAC地址转换LinkLocal地址

Blog Author 2013-08-05 IPv6

    前面介绍过 link-local 地址是通过网卡MAC地址转换而来的,这里再提供一个小程序来转换;用C语言写个程序:先获取本机MAC地址,据此得到Link Local地址( IPv6 Address )。 #include #include #include void byte2Hex(unsigned char bData,unsigned char hex[]) { int high=bData/16,low =bData %16; hex[0] = (high <10)?('0'+high):('A'+high-10); hex[1] = (low <10)?('0'+low):('A'+low-10); } int getLocalMac(unsigned char *mac) //获取本机MAC地址 { ULONG ulSize=0; PIP_ADAPTER_INFO pInfo=NULL; int temp=0; temp = GetAdaptersInfo(pInfo,&ulSize);//第一次调用,获取缓冲区大小 pInfo=(PIP_ADAPTER_INFO)malloc(ulSize); temp = GetAdaptersInfo(pInfo,&ulSize); int iCount=0; while(pInfo)//遍历每一张网卡 { // pInfo->Address 是MAC地址 ...
