[New-bugs-announce] [issue13321] fstat doesn't accept an object with "fileno" method

[Matt Joiner]

New submission from Matt Joiner <anacrolix at gmail.com>:

os.fstat doesn't not accept an object with the fileno() method.

Probably a bunch of other similar functions will not either.

In some parts of the standard library it's common practice to call PyObject_AsFileDescriptor on fd-wrapping arguments.
