I would like to retrieve the MAC address for a given NIC by using the
SIOCGENADDR ioctl, but keep getting errno 2 (ENOENT). Do I miss something or
this ioctl is broken? My next question is, how can I retrieve the MAC address
of different kinds of NIC cards?
Thanks,
Shao.
Here is the code fragment I use:
#ifdef SIOCGENADDR /* Solaris: ethernet MAC addr */
if (ioctl(sockfd, SIOCGENADDR, &ifr) == 0) {
memcpy(nic->m_haddr, ifr.ifr_enaddr, 6);
nic->m_hlen = 6;
}
#endif /* SIOCGNADDR */
