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.
