how to tell if x is an instance of new class?

[Michal Vitecek]

hello,

i'm (once again) fighting with python C API. i'm simply unable to
determine whether 'x' is an instance of new class or not.

result of PyObject_Type(x) is unusable, PyType_Check(x) returns 0,
PyType_IsSubtype(x->ob_type, &PyType_Type) returns 0,
PyType_IsSubtype((PyTypeObject *)x, &PyType_Type) returns 0...

how come there's no *easy-and-immediately-obvious* way to get such an
important information? what am i missing?

HELP!

The problem is that this question isn't terribly wll defined. Why do
you want to know?
