Finding all IPv4 addresses associated with INADDR_ANY (?)

[Ronald F. Guilmette]

Greetings,

Given a socket which has been properly created, opened, and then bound
to some port and the special INADDR_ANY ``wildcard'' address, I need
to be able to them programatically find all of the IPv4 addresses that
the socket was just bound to.

Can anyone suggest a way to do this?

Can anyone suggest a way to do this easily?

Can anyone suggest a way to do this portably?
