All,
I'm loving the shared_ptr class, however we have one issue that doesn't seem to be addressed by any of boost's smart pointers, and I'm looking for a work-around/alternative. Any help?
The issue is that the smart pointers assume the pointer type to be 'T*', which is fine on a 32-bit system, but means that we get a near doubling of run-time size on our application when we move to a 64-bit application.
As a result, we're using the standard technique to have a custom heap, and use our own 'pointers' into that heap that are smaller (typically 32-bits).
But of course our ClassOnHeapPtr type does not match a 'ClassOnHeap *', so a boost::shared_ptr<ClassOnHeap> won't work.
Are there any other libraries you boosters would recommend?
You might look at the policy-based smart_ptr implementation in the Boost sandbox. Maybe you could devise an appropriate policy for holding your "small pointer". -- Dave Abrahams Boost Consulting www.boost-consulting.com
