protocol-independant joining a multicast group

[Marcelo Taube]

I hope this is gonna be the last question i ask here,I don't wanna bother you so much.


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
