NAME         top

       rdma_get_send_comp - retrieves a completed send, read, or write

SYNOPSIS         top

       #include <rdma/rdma_verbs.h>

       int rdma_get_send_comp (struct rdma_cm_id *id, struct ibv_wc

ARGUMENTS         top

       id          A reference to a communication identifier to check
                   for completions.

       wc          A reference to a work completion structure to fill

DESCRIPTION         top

       Retrieves a completed work request for a send, RDMA read, or RDMA
       write 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.

RETURN VALUE         top

       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.

NOTES         top

       This calls polls the send 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.
