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

NAME
       rdma_post_send -	post a work request to send a message.

SYNOPSIS
       #include	<rdma/rdma_verbs.h>

       int  rdma_post_send  (struct rdma_cm_id *id, void *context, void	*addr,
       size_t length, struct ibv_mr *mr, int flags);

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.

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 remote peer of a connection.

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 remote peer has queued a
       receive request before issuing the send operations.  For	a list of sup-
       ported  flags, see ibv_post_send.  Unless the send request is using in-
       line 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.

       Send operations may not be posted to an rdma_cm_id or the corresponding
       queue pair until	it has been connected.

       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.
