# 模組物件模組

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)

  Return true if p is a module object, or a subtype of a module object.

  2.2 版更變: Allowed subtypes to be accepted.

int `PyModule_CheckExact`(PyObject *p)

  Return true if p is a module object, but not a subtype of `PyModule_Type`.

PyObject* `PyModule_New`(const 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. It is recommended extensions use other `PyModule_*()` and `PyObject_*()` functions rather than directly manipulate a module’s `__dict__`.

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, const 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. Return `-1` on error, `0` on success.

  2.0 版新加入.

int `PyModule_AddIntConstant`(PyObject *module, const char *name, long value)

  Add an integer constant to module as name. This convenience function can be used from the module’s initialization function. Return `-1` on error, `0` on success.

  2.0 版新加入.

int `PyModule_AddStringConstant`(PyObject *module, const char *name, const 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. Return `-1` on error, `0` on success.

  2.0 版新加入.

int `PyModule_AddIntMacro`(PyObject *module, macro)

  Add an int constant to module. The name and the value are taken from macro. For example `PyModule_AddIntMacro(module, AF_INET)` adds the int constant AF_INET with the value of AF_INET to module. Return `-1` on error, `0` on success.

  2.6 版新加入.

int `PyModule_AddStringMacro`(PyObject *module, macro)

  > Add a string constant to module.
