rdma_post_send - post a work request to send a message.
int rdma_post_send (struct rdma_cm_id *id, void *context, void *addr,
size_t length, struct ibv_mr *mr, int flags);
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
flags Optional flags used to control the send operation.
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.
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 remote peer 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.
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
returned to the user through the work completion wr_id, work request
rdma_cm(7), rdma_connect(3), rdma_accept(3), ibv_post_send(3),
