- [section Header <boost/core/null_deleter.hpp>]
- The header `<boost/core/null_deleter.hpp>` defines the `boost::null_deleter` function object,
- which can be used as a deleter with smart pointers such as `unique_ptr` or `shared_ptr`. The
- deleter doesn't do anything with the pointer provided upon deallocation, which makes it useful
- when the pointed object is deallocated elsewhere.
- [section Example]
- ``
- std::shared_ptr< std::ostream > make_stream()
- {
- return std::shared_ptr< std::ostream >(&std::cout, boost::null_deleter());
- }
