RDMA_MIGRATE_ID(3) Librdmacm Programmer's Manual RDMA_MIGRATE_ID(3)NAMErdma_migrate_id - Move a communication identifer to a different event
channel.
SYNOPSIS
#include <rdma/rdma_cma.h>
int rdma_migrate_id (struct rdma_cm_id *id, struct rdma_event_channel
*channel);
ARGUMENTS
id An existing communication identifier to migrate.
channel The communication channel that events associated with the
allocated rdma_cm_id will be reported on. May be NULL.
DESCRIPTION
Migrates a communication identifier to a different event channel.
RETURN VALUE
Returns 0 on success, or -1 on error. If an error occurs, errno will
be set to indicate the failure reason.
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.
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.
