How to create a writeable buffer?

I'm trying to create an object (as a C extension) to support the buffer
interface and was getting "TypeError: buffer is read-only" errors. So I
had a look at the array object and it has the same problem:
>>> import array
>>> a=array.array('c', ['a', 'b', 'c'])
TypeError: buffer is read-only
The array is a mutable (writable) object, and the array implements the
buffer interface and provides a 'getwritebuf' method.
(Python-2.4.4/Modules/arraymodule.c has an array_buffer_getwritebuf())
so why does it give "TypeError: buffer is read-only"?
