Question API to iterate over available network connections

Dear All,

Is anybody aware of some API which lets me iterate over the network connections currently active on the Linux box?

I have this scenario:
My laptop running fedora is connected simultaneously through

1. Ethernet

My program communicates over UDP with other computer on the network. Now I want my program to be in control of which network connection is used for communication.

Find the IP address assigned to the device you want to use, then bind() your port. Typically this is done by the server.

For the client application, it can perform a connect(), and then rely on send() to send messages. Alternatively, the client can use a sendto() and provide the server's IP address and port number.
