Hmmm. I was almost thinking the same thing, but I was hoping there was something I was missing. What about boost::variant? Can I stuff that into a queue in shared memory? --- Aaron Wright From: Ion Gaztañaga <igaztanaga@gmail.com> To: Boost User List <boost-users@lists.boost.org> Date: 04/03/2012 02:30 PM Subject: Re: [Boost-users] [Interprocess] Collection of base shared_ptr Sent by: boost-users-bounces@lists.boost.org El 03/04/2012 21:18, Aaron_Wright@selinc.com escribió:
I'm using Boost 1.49, and Visual Studio 10.
I'm having a hard time figuring out how to store a shared_ptr to a derived class in a collection of shared_ptr to the base class. This is something I do all the time with normal shared pointers. This is my code:
You can't do that. In shared memory there is no place for virtuality (so no room for virtual destructors essential to be able to use derived classes). boost::interproces::shared_ptr is only for reference counted semantics.
