A BDT instance only becomes available for the first time after you callBDT_CLASS_INIT BDT_INSTANCE_CREATE. It is no longer available if youcall BDT_INSTANCE_DESTROY, or BDT_CLASS_INIT again. Even dependentinstances are terminated with BDT_INSTANCE_DESTROY (secondaryinstances, sub-instances), and are no longer available for further use.
