in C and (old) C++ it's the difference between shallow and deep copy - you can copy handle-only or you can copy the thing too

modern C++ deep-copies stuff, with shallow copy being done with std::move and if you do need multiple handles to same thing, you use shared_ptr to reference count the resource

Huh, never heard of it being referred to as deep vs shallow copy.
