       rdma_post_ud_send - post a work request to send a datagram.


       #include <rdma/rdma_verbs.h>

       int  rdma_post_ud_send  (struct  rdma_cm_id  *id,  void  *context, void
       *addr, size_t length, struct ibv_mr *mr, int flags, struct ibv_ah  *ah,
       uint32_t remote_qpn);


       id          A reference to a communication identifier where the message
                   buffer will be posted.

       context     User-defined context associated with the request.

       addr        The address of the memory buffer to post.

       length      The length of the memory buffer.

       mr          Optional  registered  memory  region  associated  with  the
                   posted buffer.

       flags       Optional flags used to control the send operation.

       ah          An  address  handle  describing  the  address of the remote

       remote_qpn  The number of the destination queue pair.


       Posts a work request to the send queue of  the  queue  pair  associated
       with the rdma_cm_id.  The contents of the posted buffer will be sent to
       the specified destination queue pair.


       Returns 0 on success, or -1 on error.  If an error occurs,  errno  will
       be set to indicate the failure reason.


       The  user  is  responsible for ensuring that the destination queue pair
       has queued a receive request before issuing the send operations.  For a
       list of supported flags, see ibv_post_send.  Unless the send request is
       using inline data, the message buffer must have been registered  before
       being  posted, with the mr parameter referencing the registration.  The
       buffer must remain registered until the send completes.

       The user-defined context associated  with  the  send  request  will  be
       returned  to  the  user through the work completion wr_id, work request
       identifier, field.
