NAME         top

       rdma_leave_multicast - Leaves a multicast group.

SYNOPSIS         top

       #include <rdma/rdma_cma.h>

       int rdma_leave_multicast (struct rdma_cm_id *id, struct sockaddr
       *addr);

ARGUMENTS         top

       id          Communication identifier associated with the request.

       addr        Multicast address identifying the group to leave.

DESCRIPTION         top

       Leaves a multicast group and detaches an associated QP from the
       group.

RETURN VALUE         top

       Returns 0 on success, or -1 on error.  If an error occurs, errno
       will be set to indicate the failure reason.

NOTES         top

       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.
