| [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()); |
| } |
