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.
