@Title Implementation Callbacks for Handle Manager API

@Description Part of the handle manager API. This file is for declarations
|
and definitions that are private/internal to the handle manager
|
API but need to be shared between the generic handle manager

code and the various handle manager backends, i.e. the code that
|
implements the various callbacks.
