 .. c:function:: void* PyModule_GetState(PyObject *module)
 
    The module’s state can be stored in per‑module memory, which is obtained by calling this function.
-   This makes modules safe to use with sub‑interpreters.
 
    The amount of memory allocated for the module’s state is specified by the :c:member:`PyModuleDef.m_size` field.
 
-   The function returns a pointer to the state memory, or **NULL**
-   if the argument is not a ``PyModule`` object or
-   if the module does not support local state (i.e., :c:member:`PyModuleDef.m_size` is ``-1``).
+   The function returns a pointer to the state memory, or ``NULL``.
