Kevin Martin:
My question is whether the boost library has anywhere in it a null deleter object, or whether it is possible to define one in place with boost::lambda or similar?
boost::lambda::_1 should work as a null deleter, although you're right that we might wish to add boost::null_deleter. Can you please file a Trac ticket for this?
Just a small note. It can be pretty expensive to use a shared_ptr for stack objects. shared_ptr allocates a shared_counter on heap and shared_ptr uses by default thread safe locking. If you can pass stack objects as shared_ptr instanses, why can't you pass them as references? Thanks, Ovanes
