[issue15986] memoryview: expose 'buf' attribute

[Martin Panter]

Martin Panter added the comment:

This issue was linked from <https://mail.python.org/pipermail/python-dev/2012-September/121781.html>. I was looking for ways to pass read-only memory views into “ctypes” without copying memory, and came across that thread. Assuming this “buf” attribute points to the memory of the memory view, it could then be passed to “ctypes.c_void_p” or “_CData.from_address”.
