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 completions.

       wc          A reference to a work completion structure to fill in.

DESCRIPTION

       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.

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 failure 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 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.
