rdma_leave_multicast - Leaves a multicast group.
int rdma_leave_multicast (struct rdma_cm_id *id, struct sockaddr
id Communication identifier associated with the request.
addr Multicast address identifying the group to leave.
Leaves a multicast group and detaches an associated QP from the group.
Returns 0 on success, or -1 on error. If an error occurs, errno will
be set to indicate the failure reason.
Calling this function before a group has been fully joined results in
canceling the join operation. Users should be aware that messages
received from the multicast group may stilled be queued for completion
processing immediately after leaving a multicast group. Destroying an
rdma_cm_id will automatically leave all multicast groups.
