When you first attach a target object to a shared_ptr<T> you can also specify a deleter, which is a functor with an operator() that takes a single argument, a pointer to the target object, and deletes it. // Instances of some_type [...]]]> http://nealabq.com/blog/2008/12/02/array_deleter/feed/ 0 http://nealabq.com/blog/2008/12/01/make_shared/ http://nealabq.com/blog/2008/12/01/make_shared/#comments Mon, 01 Dec 2008 23:23:53 +0000 Neal http://nealabq.com/blog/?p=606 [...]]]> http://nealabq.com/blog/2008/12/01/make_shared/feed/ 0 http://nealabq.com/blog/2008/11/28/factory/ http://nealabq.com/blog/2008/11/28/factory/#comments Sat, 29 Nov 2008 00:12:47 +0000 Neal http://nealabq.com/blog/?p=602 (..) and allocate_shared<T>(..) standard library functions.

Boost is a very nice and carefully thought-out library, so these functions may be missing for a good reason.
