16 pletions.

21 Retrieves a completed work request for a send, RDMA read, or RDMA write
22 operation. Information about the completed request is returned through
23 the wc parameter, with the wr_id set to the context of the request.
24 For details on the work completion structure, see ibv_poll_cq.
25
27 Returns the number of returned completions (0 or 1) on success, or -1
28 on error. If an error occurs, errno will be set to indicate the fail‐
29 ure reason.

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