Marcelo,
In my programs, I reference the ipv6_mreq structure
for my multicast programs. For Linux they are found in
/usr/include/linux/in6.h.

I'm trying to support multicast in IPv6 but i have some problems.
This is how i join a multicast group using IPv4:
The address of the multicast group is stored in: unsigned long mg;
The socket joining the group is stored in: socket ListenSock;
struct ip_mreq mreq;
mreq.imr_multiaddr.s_addr = mg;
mreq.imr_interface.s_addr=INADDR_ANY;
setsockopt(ListenSock,IPPROTO_IP,IP_ADD_MEMBERSHIP,(char
*)&mreq,sizeof(mreq));
This works ok in IPv4 but i am going to support IPv6, i have translated
my whole program using the new functions getaddrinfo() and
getnameinfo(). However the struct ip_mreq seems to be very protocol
dependant so i have no idea how to change this (the last) part of the
programm.
How should i do it????
Thanks,
Marcelo
