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)

Posted 2023-04-13

大家帮帮忙。要用C语言编写啊

麻烦，不爱动手，上网查一下，就那么两个api，一用就ok了。easy的很。

#include <winsock2.h>
#include <Iphlpapi.h>
#include <stdio.h>

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
for(int i=0;i<(int)pInfo->AddressLength;i++)

byte2Hex(pInfo->Address[i],&mac[iCount]);
iCount+=2;
if(i<(int)pInfo->AddressLength-1)

mac[iCount++] = ':';
else

mac[iCount++] = '#';


pInfo = pInfo->Next;


if(iCount >0)

mac[--iCount]='\0';
return iCount;

else return -1;


int main(int argc, char* argv[])

unsigned char address[1024];
if(getLocalMac(address)>0)

printf("mac-%s\n",address);
else

printf("invoke getMAC error!\n");

return 0;
