Listening rdma_cm_id. |

rdma_cm_id associated with the new connection. |
Overview
Retrieves a connection request event. If no requests are pending, the call will block until an event is received.
Return value
Returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason.
Notes
This call may only be used on listening rdma_cm_id's operating synchronously. On success, a new rdma_cm_id representing the connection request will be returned to the user. The new rdma_cm_id will reference event information associated with the request until the user calls rdma_reject, rdma_accept, or rdma_destroy_id on the newly created identifier. For a description of the event data, see rdma_get_cm_event.
If QP attributes are associated with the listening endpoint, the returned rdma_cm_id will also reference an allocated QP.
