boost::check_delete

You'd use boost::checked_delete pretty much like you'd use delete; internally all it does is call delete anyways. It just causes a compile error if you try to delete a pointer to an incomplete type.

edit: and you use boost::checked_array_delete like you'd use delete [].

Oh. Now I realize I was looking at it wrong. I got it from this thread here and I thought it did the same thing the code snippet did, so looking at it that way I couldn't make head or tails of it [smile] makes sense now.

Well, if you want, boost::checked_deleter<> (extra r is significant) is equivalent to the function object in the first post (except again it doesn't allow the deletion of a pointer to an incomplete type).
