RDMA_MIGRATE_ID(3)    Librdmacm Programmer's Manual   RDMA_MIGRATE_ID(3)

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, struct
       rdma_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.
