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)

Return 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)

Return 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. 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, 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. New in version 2.0.

int PyModule_AddIntConstant(

PyObject *module, 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. 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. Return -1 on error, 0 on success. New in version 2.0.
