strings instead of Python :class:`str` objects.
.. versionadded:: 3.14
.. c:function:: PyObject* PyImport_CreateModuleFromInitfunc(PyObject *spec, PyObject* (*initfunc)(void))
This function is a building block that enables embedders to implement
the :py:meth:`~importlib.abc.Loader.create_module` step of custom
static extension importers (e.g. of statically-linked extensions).
*spec* must be a :class:`~importlib.machinery.ModuleSpec` object.
*initfunc* must be an :ref:`initialization function <extension-export-hook>`,
the same as for :c:func:`PyImport_AppendInittab`.
On success, create and return a module object.
This module will not be initialized; call :c:func:`!PyModule_Exec`
to initialize it.
(Custom importers should do this in their
:py:meth:`~importlib.abc.Loader.exec_module` method.)
On error, return NULL with an exception set.
