Create an aliasing managed pointer from alias targeting ptr.
Declared in <bslma_managedptr.h>
template<class ALIASED_TYPE>
ManagedPtr(
ManagedPtr<ALIASED_TYPE>& alias,
TARGET_TYPE* ptr);Create a managed pointer that takes ownership of the object managed by the specified alias, but which uses the specified ptr to refer to its target object, unless 0 == ptr, in which case create an empty managed pointer. Reset alias to empty if ownership of its managed object is transferred. The behavior is undefined if alias is empty, but 0 != ptr. Note that destroying or re-assigning a managed pointer created with this constructor will destroy the object originally managed by alias (unless release is called first); the destructor for *ptr is not called directly.
