'Return a <cdata \'char[]\'> that points to the data of the
given Python object, which must support the buffer interface.
Note that this is not meant to be used on the built-in types str,
unicode, or bytearray (you can build \'char[]\' arrays explicitly)
but only on objects containing large quantities of raw data
in some other format, like \'array.array\' or numpy arrays.'
