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.
