I tried:
find /usr/include -follow -name *.h -exec grep -l sockaddr_pkt \{\} \;
and only found one definition, in /usr/include/linux/if_packet.h . In
fact that is the only use of that symbol in the whole linux source tree
on my 2.1.115 system. Where is the other version of sockaddr_pkt
defined, and how would I know when to use one or the other?
Once I understand this stuff thoroughly, I'll write some packet-socket
documentation so that (one may hope) nobody will have to ask you again.
