Summary: getsockopt/setsockopt with SO_RCVTIMEO are inconsistent

Initial Comment:
The SO_RCVTIMEO option to getsockopt/setsockopt seems
to vary it's parameter format when used under Linux.

With setsockopt, the parameter seems to be a struct of
{long seconds, long microseconds}, as you would expect
since it's modelling a C "struct timeval".

However, with getsockopt, the parameter format seems to
be {long seconds, long milliseconds} --- ie. it uses
milliseconds rather than microseconds.

The attached python script demonstrates this problem.

Am I doing something crucially wrong, or is this meant
to happen, or ... ?

What I'm using:
Python 2.2.2 (#1, Feb 24 2003, 17:36:09)
[GCC 3.0.4 (Mandrake Linux 8.2 3.0.4-2mdk)] on linux2

What do we do about this? Since it does not seem to be an
explciitly python problem, do we just resolve it as
"Rejected" or "Wont Fix"?

Yes, you're right - the same thing happens with C.

Here's the output from sockopt.c on my system:

base (len 8) - 12, 345670
default (len 8) - 0, 0
after setsockopt (len 8) - 12, 20

I just tested this on my box (Redhat 9/Linux 2.4).  I get
similar results with a C program as Python.  (Not sure why I
didn't get exactly the same results, but I'm tired.)  So I'm
not sure Python has a problem, since it is just exposing
what is happening in C.

Take a look at the C example and try it on your box.  What
results do you get?
