a trigger for changes to network interfaces (equivalent of WSAEventSelect with FD_ADD

Hi,

Is there a way to register a socket descriptor with select, so that
one gets notified every time the underlying network interfaces change.
On Windows, I can use WSAEventSelect with FD_ADDRESS_ LIST_CHANGE to
receive notification of local address list changes for the address
family of the socket. What's the Unix equivalent for the same
functionality?

In general, is there a way to get triggered when the underlying
network connectivity changes?

Thanks so much for your time.
