Hi, Suppose I have a DLL that allocates a few objects and places them in a ptr_vector. I then pass this ptr_vector to my executable via a move operation (basically a swap, not a copy). The executable would keep the ptr_vector by value and eventually delete it when it falls out of scope.
Hi Robert,
I have checked in a new version in trunk that supports stateful clone_allocators.
You may access the clone_allocator by
clone_allocator& get_clone_allocator();
I prefer this to a constructor argument, since there are already so many constructors.
Let me know if this allows you to solve your problem.
Thanks Thorsten, I'm not familiar with how to use clone allocators in ptr_container yet, so I'll have to read through the documentation first to make sure I know how to use them. Given that, at what point will I need to be calling get_clone_allocator()? I figured I would just give ptr_vector my clone allocator and never need it back from the container. I expect my clone allocator to call the appropriate allocation method in its implementation details, which as I showed in an earlier example, will be a function located in the DLL itself.
