[C++-sig] call policies

[Stefan Seefeld]

hi there,

I'm reading up on call policies but I'm not sure my case is
covered there:

I'v got an object handed back from a factory call. I pass
this object to another object where the second one takes
over ownership:

Foo *foo = FooFactory();
Bar *bar = BarFactory(foo);

(with either

Bar *BarFactory(Foo *);

or

Bar *BarFactory(auto_ptr<Foo>);

signature. How do I express that in boost.python ? The
'custody_and_wart' policy expects two arguments, the object
to be consumed as well as the consuming one. In my case
the consumer is created in the call. Which policy do I need ?

Thanks,
		Stefan
