int rdma_get_recv_comp (struct rdma_cm_id *id, struct ibv_wc *wc);
id A reference to a communication identifier to check for
wc A reference to a work completion structure to fill in.
Retrieves a completed work request for a receive operation.
Information about the completed request is returned through the wc
parameter, with the wr_id set to the context of the request. For

This calls polls the receive completion queue associated with an
rdma_cm_id. If a completion is not found, the call blocks until a
request completes. This call should only be used on rdma_cm_id's that
do not share CQs with other rdma_cm_id's, and maintain separate CQs for
sends and receive completions.
