It is difficult (or actually impossible) to answer this, if you do not
explain which concept you are talking about here, or why two copy
operations would be needed, what "in case of DM" means (and which
other cases exist), or how you intend to handle the problem of
changing addresses (and thus pointers becoming incorrect) for each of
such copy operations.

Best regards,

Wolfgang Denk
