    MyDataBlock(const CAP_Shmem_Void_Alloc& alloc)

    {

        /*

        My question is how do I convert CAP_Shmem_Void_Alloc to type CAP_Shmem_String_Alloc to call allocate? And do I pass in the void allocator as a construction argument? Is there a difference between allocate and construct?

        */

    }

    ~MyDataBlock()

    {

        /*

        To delete the memory, do I need to keep around a copy of the original allocator, so I can call deallocate or destroy? Or can that be derived or converted from somewhere, like calling strData->alloc() ?

    

        */

Any help would be greatly appreciated.

Thank you.
