rdma_migrate_id: Move a communication identifer to a different event channel.
rdma_migrate_id - Move a communication identifer to a different event channel.
(struct rdma_cm_id *id,
struct rdma_event_channel *channel);
An existing communication identifier to migrate.
The communication channel that events associated with the
allocated rdma_cm_id will be reported on. May be NULL.
Migrates a communication identifier to a different event channel.
Returns 0 on success, or -1 on error. If an error occurs, errno will be
set to indicate the failure reason.
This routine migrates a communication identifier to the specified event
channel and moves any pending events associated with the rdma_cm_id
to the new channel. Users should not poll for events on the
rdma_cm_id's current event channel or invoke other routines on the
rdma_cm_id while migrating between channels. This call will block while
there are any unacknowledged events on the current event channel.
If the channel parameter is NULL, the specified rdma_cm_id will be
placed into synchronous operation mode. All calls on the id
will block until the operation completes.
