Hi Scott, This is regular use of polymorphism through virtual member functions : you **dynamically** allocate whatever subclass of std::ostream (e.g., std::ofstream) and you store the returned pointer value into a pointer to base class (std::ostream*). When deleting this pointer, independently from the type of the variable you call delete on, the virtual destructor mechanism will ensure the destructor of the subclass you allocated is called.
Thus, you could call delete on _stream and have your stream properly closed. Having said that, I would strongly advise against manual use of new and delete, especially when you are not the owner of the pointer you are playing with. Just call flush on the stream. This eventually synchronizes the most derived class through pubsync (https://en.cppreference.com/w/cpp/io/basic_ostream/flush).
