^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Some shared libraries not only export functions, they also export variables. An
example in the Python library itself is the :c:data:`Py_OptimizeFlag`, an integer
set to 0, 1, or 2, depending on the :option:`-O` or :option:`-OO` flag given on
startup.
example in the Python library itself is the :c:data:`Py_Version`, Python
runtime version number encoded in a single constant integer.

:mod:`ctypes` can access values like this with the :meth:`in_dll` class methods of
the type. *pythonapi* is a predefined symbol giving access to the Python C
api::

>>> opt_flag = c_int.in_dll(pythonapi, "Py_OptimizeFlag")
>>> print(opt_flag)
c_long(0)
>>>
>>> version = ctypes.c_int.in_dll(ctypes.pythonapi, "Py_Version")
>>> print(hex(version.value))

If the interpreter would have been started with :option:`-O`, the sample would
have printed ``c_long(1)``, or ``c_long(2)`` if :option:`-OO` would have been
