7.5.4 Module Objects

There are only a few functions special to module objects.

PyTypeObject `PyModule_Type`
  This instance of `PyTypeObject` represents the Python module type. This is exposed to Python programs as `types.ModuleType`.

int `PyModule_Check`(PyObject *p)
  Returns true if p is a module object, or a subtype of a module object. Changed in version 2.2: Allowed subtypes to be accepted.

int `PyModule_CheckExact`(PyObject *p)
  Returns true if p is a module object, but not a subtype of `PyModule_Type`. New in version 2.2.

PyObject* `PyModule_New`(char *name)
  Return value: New reference.
  Return a new module object with the `__name__` attribute set to name. Only the module's `__doc__` and `__name__` attributes are filled in; the caller is responsible for providing a `__file__` attribute.

PyObject* `PyModule_GetDict`(PyObject *module)
  Return value: Borrowed reference.
  Return the dictionary object that implements module's namespace; this object is the same as the `__dict__` attribute of the module object. This function never fails.

char* `PyModule_GetName`(PyObject *module)
  Return module's `__name__` value. If the module does not provide one, or if it is not a string, `SystemError` is raised and `NULL` is returned.

char* `PyModule_GetFilename`(PyObject *module)
  Return the name of the file from which module was loaded using module's `__file__` attribute. If this is not defined, or if it is not a string, raise `SystemError` and return `NULL`.

int `PyModule_AddObject`(PyObject *module, char *name, PyObject *value)
  Add an object to module as name. This is a convenience function which can be used from the module's initialization function. This steals a reference to value. Returns `-1` on error, `0` on success. New in version 2.0.

int `PyModule_AddIntConstant`(PyObject *module, char *name, int value)
  Add an integer constant to module as name. This convenience function can be used from the module's initialization function. Returns `-1` on error, `0` on success. New in version 2.0.

int `PyModule_AddStringConstant`(PyObject *module, char *name, char *value)
  Add a string constant to module as name. This convenience function can be used from the module's initialization function. The string value must be null-terminated. Returns `-1` on error, `0` on success. New in version 2.0.
