IBV_ATTACH_MCAST(3)					  Libibverbs Programmer's Manual				       IBV_ATTACH_MCAST(3)

NAME

       ibv_attach_mcast, ibv_detach_mcast - attach and detach a queue pair (QPs) to/from a multicast group

SYNOPSIS

       #include <infiniband/verbs.h>

       int ibv_attach_mcast(struct ibv_qp *qp, const union ibv_gid *gid,
			    uint16_t lid);

       int ibv_detach_mcast(struct ibv_qp *qp, const union ibv_gid *gid,
			    uint16_t lid);

DESCRIPTION

       ibv_attach_mcast() attaches the QP qp to the multicast group having MGID gid and MLID lid.

       ibv_detach_mcast() detaches the QP qp to the multicast group having MGID gid and MLID lid.

RETURN VALUE

       ibv_attach_mcast() and ibv_detach_mcast() returns 0 on success, or the value of errno on failure (which indicates the failure reason).

NOTES

       Only QPs of Transport Service Type IBV_QPT_UD may be attached to multicast groups.

       If a QP is attached to the same multicast group multiple times, the QP will still receive a single copy of a multicast message.

       In  order  to receive multicast messages, a join request for the multicast group must be sent to the subnet administrator (SA), so that the
       fabric's multicast routing is configured to deliver messages to the local port.
