The purpose is to dump the contents of a Python extension type to disk
as binary data using C's fwrite() function.
This isn't really possible anymore - the Python IO library has stopped
using stdio. There are a couple of alternatives:
1. don't use fwrite(3) to write the binary data, but
In Python2.x, I used PyFile_Check(obj) to check if a parameter was a
file object.
Now, in Python3.0 the same object (obtained as open('file.bin','wb'))
is an
io.BufferedWriter object.
How do I perform type checking for such an object in the extension
module,
and how do I extract a FILE * object

You use PyObject_IsInstance to test if the object is an

But you have to import the io module first, don't you? That's not
