RDMA_POST_UD_SEND(3)	 Librdmacm Programmer's	Manual	  RDMA_POST_UD_SEND(3)

NAME
       rdma_post_ud_send - post	a work request to send a datagram.

SYNOPSIS
       #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);

ARGUMENTS
       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
		   node.

       remote_qpn  The number of the destination queue pair.

DESCRIPTION
       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.

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

NOTES
       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  re-
       turned  to  the	user  through  the work	completion wr_id, work request
       identifier, field.
