RDMA_LEAVE_MULTICAST(3)  Librdmacm Programmer's Manual RDMA_LEAVE_MULTICAST(3)

NAME
       rdma_leave_multicast - Leaves a multicast group.

SYNOPSIS
       #include <rdma/rdma_cma.h>

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

ARGUMENTS
       id          Communication identifier associated with the request.

       addr        Multicast address identifying the group to leave.

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

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

NOTES
       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.
