NAME

6       rdma_migrate_id  - Move a communication identifier to a different event
7       channel.
8

SYNOPSIS

10       #include <rdma/rdma_cma.h>
11
12       int rdma_migrate_id (struct rdma_cm_id *id,  struct  rdma_event_channel
13       *channel);
14

ARGUMENTS

16       id          An existing communication identifier to migrate.
17
18       channel     The  communication  channel that events associated with the
19                   allocated rdma_cm_id will be reported on.  May be NULL.
20

DESCRIPTION

22       Migrates a communication identifier to a different event channel.
23

RETURN VALUE

25       Returns 0 on success, or -1 on error.  If an error occurs,  errno  will
26       be set to indicate the failure reason.
27

NOTES

29       This routine migrates a communication identifier to the specified event
30       channel and moves any pending events associated with the rdma_cm_id  to
31       the  new channel.  Users should not poll for events on the rdma_cm_id's
32       current event channel or invoke other routines on the rdma_cm_id  while
33       migrating  between  channels.  This call will block while there are any
34       unacknowledged events on the current event channel.
35
36       If the channel parameter is NULL,  the  specified  rdma_cm_id  will  be
37       placed into synchronous operation mode.  All calls on the id will block
38       until the operation completes.
