I understand your concern, still, in my eyes COW is just another application of the handle/body pattern and thus not /that/ far away from the scope of this submission. [...]
From my experience, you don't because at that point you would use some other kind of pointer. Most likely a reference counted pointer that can travel across DLL boundaries. template<typename T> void dispose_func(void* ptr) { delete static_cast<T*>(ptr); }
Yes I do know how the DLL boundary issue is solve ;-) My point is the reference counting... What is being suggested, by you and others, is to have a reference counted pointer with deep copy semantics implemented as copy on write for efficiency. And in my opinion at that point you are looking at the territory of shared_ptr/weak_ptr, and hence outside of the intended scope of the pimpl_ptr submission. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo
