Hello, i need to give up the ownership of a ptr_container (vector here) over its pointers (without assignment to a new ptr_container). Two questions here: 1. Do i really have to write aPtrContainer.release().release()? It looks weird. For me, the function name release() of the container seems confusing since an unassigned aPtrContainer.release() just does the "opposite" of auto_ptr<T>::release(), namely deleting the pointers. ;o) The behavior is more like transfer_ownership() or something similar ($0.02). 2. Beside managing memory, i plan to use ptr_container primarily to propagate const. So, in some cases i need a ptr_container which just doesn't own any given memory. What's the best way to do that? Any comments or pointers to missed docs are welcome. David
