Имя (Name)
rdma_post_send - post a work request to send a message.
Синопсис (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);
Аргументы (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.
Описание (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.
Возвращаемое значение (Return value)
Returns 0 on success, or -1 on error. If an error occurs, errno
will be set to indicate the failure reason.
Примечание (Note)
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 identifier, field.
