IBV_ATTACH_MCAST(3) Libibverbs Programmer's Manual IBV_ATTACH_MCAST(3)NAMEibv_attach_mcast, ibv_detach_mcast - attach and detach a queue pair (QPs) to/from a multicast groupSYNOPSIS#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);DESCRIPTIONibv_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 VALUEibv_attach_mcast() and ibv_detach_mcast() returns 0 on success, or the value of errno on failure (which indicates the failure reason).NOTESOnly 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.SEE ALSOibv_create_qp(3)AUTHORSDotan Barak <dotanba@gmail.com> libibverbs 2006-10-31 IBV_ATTACH_MCAST(3)
