NAME

       rdma_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.
