Create a shared pointer that manages a modifiable object of (template parameter) type CONVERTIBLE_TYPE, refers to the specified ptr cast to a pointer to the (template parameter) type ELEMENT_TYPE, and uses the specified deleter to delete the shared object when all references have been released. Use the currently installed default allocator to allocate and deallocate the internal representation of the shared pointer, unless DELETER is a class derived from either bslma::Allocator or bslma::SharedPtrRep; if DELETER is a class derived from bslma::allocator, create a shared pointer as if calling the constructor: ` template <class CONVERTIBLE_TYPE> shared_ptr(CONVERTIBLE_TYPE *ptr, BloombergLP::bslma::Allocator *basicAllocator); ` If DELETER is a class derived from bslma::SharedPtrRep, create a shared pointer as if calling the constructor: ` shared_ptr(ELEMENT_TYPE *ptr, BloombergLP::bslma::SharedPtrRep *rep); ` If DELETER does not derive from either bslma::Allocator or BloombergLP::bslma::SharedPtrRep, then deleter shall be a pointer to a factory object that exposes a member function that can be invoked as deleteObject(ptr) that will be called to destroy the object at the ptr address (i.e., deleter->deleteObject(ptr) will be called to delete the shared object). (See the "Deleters" section in the component-level documentation.) If CONVERTIBLE_TYPE * is not implicitly convertible to ELEMENT_TYPE *, then a compiler diagnostic will be emitted indicating the error. If ptr is 0, then the null pointer will be reference counted, and the deleter will be called when the last reference is destroyed. If an exception is thrown when allocating storage for the internal representation, then deleter(ptr) will be called. Note that this method is a BDE extension and not part of the C++ standard interface.
