Question
I m able to retrieved active TCP and UDP connection using iphlpapi. The TCP Connection showing with source info(ip/port), Destination info(ip/port), state and process id. But for UDP Connection its no giving remote IP and port. That what i want to get. Any way to get destination information using source information or process id in Delphi or c++.
Solution
UDP is a connectionless protocol. You can only get the local port that has been opened.
UPDATE: This applies for a static look at the port usage. However, if you have active UDP trafic you can still retrieve the remote endpoint.
