+A new calling convention tells :mod:`ctypes` to clear the ``errno`` or
+Win32 LastError variables at the outset of each wrapped call.
+(Implemented by Thomas Heller; :issue:`1798`.)
+
+For the Unix ``errno`` variable: when creating a wrapped function,
+you can supply ``use_errno=True`` as a keyword parameter
+to the :func:`DLL` function
+and then call the module-level methods :meth:`set_errno`
+and :meth:`get_errno` to set and retrieve the error value.  
+
+The Win32 LastError variable is supported similarly by
+the :func:`DLL`, :func:`OleDLL`, and :func:`WinDLL` functions.
+You supply ``use_last_error=True`` as a keyword parameter
+and then call the module-level methods :meth:`set_last_error`
+and :meth:`get_last_error`.  
+
+The :func:`byref` function, used to retrieve a pointer to a ctypes
+instance, now has an optional **offset** parameter that is a byte
+count that will be added to the returned pointer.
