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? thanks for any info... TJ -- Trey Jackson tjackson@ichips.intel.com "This is gonna cost me." -- Homer
