Code:
int getmacaddress(char* dev, unsigned char *ipmac);

int main()
{
    int mac;
    unsigned char dot_not_mac[25];
    mac=getmacaddress("eth0",dot_not_mac);
    printf(" the MAC address is %s\n",dot_not_mac);
    return 0;
}

int getmacaddress(char* dev,unsigned char *ipmac)
{
	int skfd=0;
	struct ifreq ifr;

	strcpy(ifr.ifr_name,dev);
	skfd = socket(AF_INET,SOCK_DGRAM,0);
	if(skfd<0)
	{
		DEBUG1("Can't open socket!\n");
		return -1;
	}
	if(ioctl(skfd, SIOCGIFHWADDR, &ifr) < 0)
	{
		DEBUG1("Can't read local mac address!\n");
		return -1;
	}

	memcpy(ipmac,ifr.ifr_hwaddr.sa_data,6);
      	close(skfd);
	return 0;
}
the output of the code is as below....
