Dear all,

I have an application which would probably benefit from multicasting. I tried to find out how to implement that. However, I found stuff like



int rdma_join_multicast(struct rdma_cm_id *id, struct sockaddr *addr,
                                                    void *context)
{
         return rdma_seterrno(ENOSYS);
}

in the source code, wherefore I wonder whether multicasting is supported at all on Windows. Also, samples like mckey are not included in the build.

If multicasting works, is there any Windows sample out there on how to do it? Which API can I use? To be honest, I have never used multicasting before. Does it work just with the well-known IPv4 multicast addresses on IB, too?

Thanks in advance,
Christoph
