NAME

       rdma_get_send_comp - retrieves a completed send, read, or write request.

SYNOPSIS

       #include <rdma/rdma_verbs.h>

       int rdma_get_send_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  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

       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 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.
