Detailed Description

null_deleter means "doesn't delete" rather than "deletes nulls".

Sometimes it is desirable to create a shared_ptr to an already existing object, so that the shared_ptr does not attempt to destroy the object when there are no more references left. As an example, the factory function:

shared_ptr<X> createX(); in certain situations may need to return a pointer to a statically allocated X instance.

The solution is to use a custom deleter that does nothing:
