[C++-sig] Getting object for PyObject (reference counting)

I can't find any definitive documentation that tells me how I should get a boost::python::object to wrap an existing PyObject*. I guess that there's a way to do it that uses an existing reference, and a way that takes an extra reference. -- [email protected] www.murrayc.com www.openismus.com _

Re: [C++-sig] Getting object for PyObject (reference counting)

Oh, I assumed that boost::python::object did this already. It does. Think of bp::handle<> as a low-level, bare-bones, smart PyObject*. Think of bp::object as that, *plus* all the fancy c++ API that maps to python API (like obj.attr("foo"), []-operator, ()-operator, etc). I believe bp::obj
