Well, just like Greg said, this is not much different than using the
buffer interface directly. While the above would be a handy
PyObject_WriteAsBuffer() kind of helper, I don't think that this
is really used all that much. E.g. in mxODBC I use the APIs
for accessing the raw char data in a buffer: the pointer is passed
directly to the ODBC APIs without copying, which makes things
quite fast. IMHO, this is the greatest advantage of the buffer
interface.
