Re: [boost] shared_ptr / auto_ptr

Daniel Frey:

Hi,

is there any reason why shared_ptr does not have a ctor that takes an auto_ptr and a deleter?

shared_ptr assumes that an object that is owned by an auto_ptr needs to be destroyed by delete, because that is what the auto_ptr would do if, for example, an exception is thrown before the line that transfers the ownership to a shared_ptr.

I also wonder if there is a resource leak if I just write:

auto_ptr<T> a = ...; my_deleter d = ...;

shared_ptr<T> s( a.release(), d );

No, there isn't.
