I maintain an application that uses libpcap to receive frames, and uses its own

currently support packet socket (Linux), BPF (BSD) and DLPI (Solaris).
I'd like to use libpcap to send as well as receive frames, and notice that
libpcap supports pcap_sendpacket() and pcap_inject() to do this. But I can't
find any portable way to obtain the interface IP address and MAC address.
Does libpcap allow me to get the interface IP address and MAC address?
Why should it need to?
The interfaces used to do both of the above are almost universal now:
SIOCGIFADDR and SIOCGIFHWADDR.
