NAME        top

       rdma_migrate_id - Move a communication identifier to a different       event channel.

SYNOPSIS        top

#include <rdma/rdma_cma.h>int rdma_migrate_id (struct rdma_cm_id *id, structrdma_event_channel *channel);

ARGUMENTS        top

       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        top

       Migrates a communication identifier to a different event channel.

RETURN VALUE        top

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

NOTES        top

       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.
