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.
