7

SYNOPSIS

9       #include <rdma/rdma_verbs.h>
10
11       int  rdma_post_sendv  (struct  rdma_cm_id  *id,  void  *context, struct
12       ibv_sge *slg, int nsge, int flags);
13

ARGUMENTS

15       id          A reference to a communication identifier where the message
16                   buffer will be posted.
17
18       context     User-defined context associated with the request.
19
20       slg         A  scatter-gather list of memory buffers posted as a single
21                   request.
22
23       nsge        The number of scatter-gather entries in the slg array.
24
25       flags       Optional flags used to control the send operation.
26

DESCRIPTION

28       Posts a work request to the send queue of  the  queue  pair  associated
29       with  the  rdma_cm_id.  The contents of the posted buffers will be sent
30       to the remote peer of a connection.
31

RETURN VALUE

33       Returns 0 on success, or -1 on error.  If an error occurs,  errno  will
34       be set to indicate the failure reason.
35

NOTES

37       The  user is responsible for ensuring that the remote peer has queued a
38       receive request before issuing the send operations.  For a list of sup‐
39       ported  flags,  see  ibv_post_send.   Unless  the send request is using
40       inline data, the message buffers must have been registered before being
41       posted,  and  the  buffers  must  remain registered until the send com‐
42       pletes.
43
44       Send operations may not be posted to an rdma_cm_id or the corresponding
45       queue pair until it has been connected.
46
47       The  user-defined  context  associated  with  the  send request will be
48       returned to the user through the work completion  wr_id,  work  request
49       identifier, field.
