[section:null_deleter 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.
|
|
|
|
Example
|
|
|
|
std::shared_ptr< std::ostream > make_stream()
|
|
{
|
|
return std::shared_ptr< std::ostream >(&std::cout, boost::null_deleter());
|
|
}
