Summary: os.ttyname() accepts wrong arguments

Initial Comment:
Problem:
  The doc for os.ttyname says it accepts an fd
What Happens:
  It raises a type error and says it expects an integer
instead.
  Experimentally, it seems to accept fd.fileno() as input
What should happen:
  It should an accept an fd (file object)

I have attached a test case for this.

The output I get using python 2.2 & 2.3 is:
Documentation Sez:
------------------------------------------------------------
ttyname(fd) -> String
Return the name of the terminal device connected to 'fd'.
------------------------------------------------------------

TTY Name (should work):    exceptions.TypeError an
integer is required
TTY Name (shouldn't work): /dev/pts/2

Ciao!

No, file descriptors are small integers corresponding to a
file opened by the current process.  File descriptors are
not the same as file objects; as you've discovered, you can
get the file descriptor for a file object by calling the
.fileno() method.
