Determine type of a socket

[Tor Erik Sønvisen]

Hi

How can I determine the type of a socket (TCP or UDP) object?

How can I determine the type of a socket (TCP or UDP) object?

In what context? Do you have some code that gets passed a socket object
but it could have been created with either SOCK_STREAM or SOCK_DGRAM?
And you want a way of determining by looking just at the object passed
in which type it is? (I could make other guesses, but let's start with
that... ;-) )

How about this:
['__class__', .... '_sock', 'accept', 'bind', 'close'
, 'connect', 'connect_ex', 'dup', 'fileno', 'getpeername',
....'setblocking', 'setsockopt', 'settimeout', 'shutdown']

Let's see... what looks good here?
<socket object, fd=1912, family=2, type=1, protocol=0>

Maybe that type field?

Heh. The type field isn't publicly accessible (yet). There is a
patch on SF for this, in the meanwhile you'll have to parse the
__repr__ output.

And he might not have to do either, depending on what his situation
really is. For example, if his socket is always going to be connected
(in the case of a TCP socket) I expect checking something about the peer
would be a quick way to tell the difference, since UDP sockets don't
shouldn't have peers. (I'm assuming, not having tested... but I think
there are probably such approaches that don't involve either _sock or
repr(). Let's see what the OP reveals.)
