RDMA_GET_RECV_COMP(3) Librdmacm Programmer's Manual RDMA_GET_RECV_COMP(3) NAME rdma_get_recv_comp - retrieves a completed receive request. SYNOPSIS #include <rdma/rdma_verbs.h> int rdma_get_recv_comp (struct rdma_cm_id *id, struct ibv_wc *wc); ARGUMENTS id A reference to a communication identifier to check for com- pletions. wc A reference to a work completion structure to fill in. DESCRIPTION Retrieves a completed work request for a receive operation. Informa- tion 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. RETURN VALUE 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 fail- ure reason. NOTES This calls polls the receive completion queue associated with an rdma_cm_id. If a completion is not found, the call blocks until a re- quest 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.
