RDMA_POST_SENDV(3) Librdmacm Programmer's Manual RDMA_POST_SENDV(3)
rdma_post_sendv - post a work request to send a message.
#include <rdma/rdma_verbs.h>
int rdma_post_sendv (struct rdma_cm_id *id, void *context, struct
ibv_sge *slg, int nsge, int flags);
id A reference to a communication identifier where the
message buffer will be posted.
context User-defined context associated with the request.
slg A scatter-gather list of memory buffers posted as a
single request.
nsge The number of scatter-gather entries in the slg
array.
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
buffers 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 buffers must have been
registered before being posted, and the buffers 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 identifier, field.
