.SH NAME
|
|
rdma_migrate_id \- Move a communication identifier to a different event channel.
|
|
.SH SYNOPSIS
|
|
.B "#include <rdma/rdma_cma.h>"
|
|
.P
|
|
.B "int" rdma_migrate_id
|
|
.BI "(struct rdma_cm_id *" id ","
|
|
.BI "struct rdma_event_channel *" channel ");"
|
|
.SH ARGUMENTS
|
|
.IP "id" 12
|
|
An existing communication identifier to migrate.
|
|
.IP "channel" 12
|
|
The communication channel that events associated with the
|
|
allocated rdma_cm_id will be reported on. May be NULL.
|
|
.SH "DESCRIPTION"
|
|
Migrates a communication identifier to a different event channel.
|
|
.SH "RETURN VALUE"
|
|
Returns 0 on success, or -1 on error. If an error occurs, errno will be
|
|
set to indicate the failure reason.
|
|
.SH "NOTES"
|
|
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.
|
|
.P
|
|
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.
