[C++-sig] Whats going on under the hood?

[David Sveningsson]

I want to understand how python/boost handles the memory.

Take a look at the following code:

void add(Base& e){
     list->add(e);	// Permanently stores the object
}

BOOST_PYTHON_MODULE(Foo){
     def("add", &add);

     class_<Base>("Base")

     ;
}

and this:

class Derived (Foo.Base):
     pass

add(Derived())

What happens when this code is run? What happens when the python scope 
ends? May I safely use the reference in C++? Should I delete the 
reference afterwards? What happens if I delete the reference, does it 
delete memory allocated from python too?

I should mention that I'm not really familiar with how python manages 
the memory either. Reference counting?

I hope to get some answers to my questions.
