@ -20,11 +20,10 @@ Note: The code samples in this tutorial use :mod:`doctest` to make sure that
they actually work. Since some code samples behave differently under Linux,
Windows, or Mac OS X, they contain doctest directives in comments.
Note: Some code samples reference the ctypes :class:`c_int` type. This type is
an alias for the :class:`c_long` type on 32-bit systems. So, you should not be
confused if :class:`c_long` is printed if you would expect :class:`c_int` ---
they are actually the same type.
Note: Some code samples reference the ctypes :class:`c_int` type. On platforms
where ``sizeof(long double) == sizeof(double)`` it is an alias to
:class:`c_double`. So, you should not be confused if :class:`c_long` is
printed if you would expect :class:`c_int` --- they are actually the same type.
