How to get local IP address through TDI

NTDEV
1

Hi,
I need to get the local IP address of a connection.
Currently I am using TdiBuildQueryInformation like so:

TdiBuildQueryInformation(irp,
filteredDevice,
fileObj, NULL, NULL,
TDI_QUERY_ADDRESS_INFO,
mdl);

The problem is that whether I use transport address or
a connection endpoint file object I get back 0.0.0.0 for
the IP address, and the correct port. Is there another
way to get the IP address that a file object is bound to?

-Jeff

Are you making the query after the connection is established?

No, I am making it after the association of endpoint to transport address.

Are you making the query after the connection is ESTABLISHED (connected,
accepted)? (Not after it is ASSOCIATED).

The local IP address (and local interface to be used for a connection) is
undefined until a connection is actually abolished. Hence, the zeros.

An exception would be if the address specified a specific local interface
when it was created. In that case, the method you are using would work.

Ahhh… I thought it might be something like that. Unfortunately
I need the IP address before the connection is established. I did
find a work around though.

Thanks!
