How can I found out (in C or at the commandline) what the gateway
address is that is attached to a particular interface on a multihomed
system?
If en0 is attached to one gateway and en1 to another, how can I get
the address of each unique gateway at will?
In other words, how would I answer the following question: "What is
the address of the gateway G(X) attached to interface X ?"
I need to know the C calls, but if all you know is how to do it at
the commandline, that will work, since I can look up the code for
that tool in the Darwin CVS tree.
That said, if you know both ways, of course the C way would be a
shorter path for me to take.
