It is a good idea to use this macro whenever decrementing the reference
count of an object that might be traversed during garbage collection.
.. c:function:: void Py_IncRef(PyObject *o)
Increment the reference count for object *o*. A function version of :c:func:`Py_XINCREF`.
It can be used for runtime dynamic embedding of Python.
.. c:function:: void Py_DecRef(PyObject *o)
Decrement the reference count for object *o*. A function version of :c:func:`Py_XDECREF`.
It can be used for runtime dynamic embedding of Python.
The following functions are for runtime dynamic embedding of Python:
``Py_IncRef(PyObject *o)``, ``Py_DecRef(PyObject *o)``. They are
simply exported function versions of :c:func:`Py_XINCREF` and
:c:func:`Py_XDECREF`, respectively.
The following functions or macros are only for use within the interpreter core:
:c:func:`_Py_Dealloc`, :c:func:`_Py_ForgetReference`, :c:func:`_Py_NewReference`,
