Summary: Missing 4 socket object properties

Initial Comment:
The C socketmodule has a struct PySocketSockObject, 
with family, type and proto members.

These would be terribly helpful to have access to in 
Python, when implementing some generic socket helper 
functions.

The "blocking" flag could also be made available, but 
would require some extra coding.

(I'm using Python 2.1.3 under Linux 2.4.16, so I cannot 
extend the socket class itself ((as in py2.2)), and don't 
want to slow down sockets with a complete wrapper, as I 
use them heavily.)

Thanks, Graham.

The patch applies, compiles, runs OK for me (thanks).

However it does not add access to the blocking flag.
Under Linux I can go:
    fcntl.fcntl(fd, fcntl.F_GETFL) & os.O_NDELAY != 0
But this is not portable, and is probably repeating code.

Also the 3 added members are not available from an instance
of the _socketobject wrapper, you have to go
mysock._sock.family.
(The _socketobject wrapper in socket.py is a little bizarre
IMVHO.)
Perhaps they could be added using instances of property().

Attaching a patch which implements the three members of
_socket.socket.

Please review.

Sounds good. Would you like to produce a patch implementing
this feature?

Oh yes, the repr of a socket object includes the missing info, 
so to get hold of the family, I go:
  int(repr(sock).split(' ')[3].split('=')[1][:-1])

Similar for type and protocol, not nice!
