No :-( That is a *big* problem with netlink, and I went through the same journey as you (although probably spent less time, as you sent your first message when I'd only been looking at it for a day or so). I *think* there is a libnl cache that can be used to retrieve the multicast list (look for the libnl-devel mailing list archives for a message I sent there several days ago, along with a couple of responses), but it's definitely not as straightforward as reading a file in /proc. -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
