This variant on ``s`` stores into two C variables, the first one a pointer to a
character string, the second one its length. In this case the Python string may
contain embedded null bytes. Unicode objects pass back a pointer to the default

``s*`` (string, Unicode, or any buffer compatible object) [Py_buffer \*]
Similar to ``s#``, this code fills a Py_buffer structure provided by the caller.
The buffer gets locked, so that the caller can subsequently use the buffer even
