I have tried the one-to-many code example in the draft and discovered that the

Sorry, I didn't look at the example carefully. I assume you are seeing
"Operation not supported .."? recvmsg() on one-to-many requires the
the msg_name in the msghdr struct to be non-null (and hence, msg_namelen
to be non-zero).
One more question: How to get the association ID as a client? Call connect
first? or call sctp_sendmsg first then using getsockopt to get the association
ID?
You can get the association id by subscribing to the sctp_association_event.
recvmsg() after connect()/sendmsg() will get the notification after the
association is established and the id can be obtained from the
sctp_assoc_change structure.
