That's not possible. (c)StringIO presents a file-like interface at the Python level, but under the covers, it's not implemented using anything like a normal file; thus, it doesn't have a presence on any filesystem. I would suggest using a temporary file (http://docs.python.org/library/tempfile.html ) for communicating with the C module, writing the contents of the StringIO object to the temporary file if necessary. (It's probably also possible to hack something together with FUSE, but it'd be a slow, platform-specific kludge.)
