- PyTypeObject
- The C structure of the objects used to describe built-in types.
- PyObject* PyType_Type
- This is the type object for type objects; it is the same object as
types.TypeType
in the Python layer.
-
| int PyType_Check( |
PyObject *o) |
- Returns true if the object o is a type object, including instances of types
derived from the standard type object. Returns false in all other cases.
-
| int PyType_CheckExact( |
PyObject *o) |
- Returns true if the object o is a type object, but not a subtype of the
standard type object. Returns false in all other cases. New in
version 2.2.
-
| int PyType_HasFeature( |
PyObject *o, int feature) |
- Returns true if the type object o sets the feature feature. Type
features are denoted by single bit flags.
-
| int PyType_IS_GC( |
PyObject *o) |
- Return true if the type object includes support for the cycle detector; this tests the
type flag Py_TPFLAGS_HAVE_GC. New in
version 2.0.
-
| int PyType_IsSubtype( |
PyTypeObject *a, PyTypeObject *b) |
- Returns true if a is a subtype of b. New

-
| PyObject* PyType_GenericAlloc( |
PyTypeObject *type, int nitems) |
-
Return value: New reference.

-
| PyObject* PyType_GenericNew( |
PyTypeObject *type, PyObject *args, PyObject *kwds) |
-
Return value: New reference.

-
| int PyType_Ready( |
PyTypeObject *type) |
- Finalize a type object. This should be called on all type objects to finish their
initialization. This function is responsible for adding inherited slots from a type's base
class. Returns
0 on success, or returns -1 and sets an exception
