RDMA_GET_RECV_COMP(3) Librdmacm Programmer's ManualRDMA_GET_RECV_COMP(3)
rdma_get_recv_comp - retrieves a completed receive request.
#include <rdma/rdma_verbs.h>
int rdma_get_recv_comp (struct rdma_cm_id *id, struct ibv_wc
*wc);
id A reference to a communication identifier to check
for completions.
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 details on the work completion structure, see ibv_poll_cq.
Returns the number of returned completions (0 or 1) on success,
or -1 on error. If an error occurs, errno will be set to
indicate the failure reason.
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.
