Answer 1

From the looks of your code you are not doing connect or accept on the socket. Until you have done this the data you get from getsockname is undefined.

Answer 2

I don't think you can meaningfully call getsockname in this context until you've called connect() - the kernel doesn't bind it to a particular port until it needs to (or is told to do so explicitly), and the local address is chosen based on the routing table, and hence the destination.
