I've not managed to get a survey of other environments done
so I'd like to ask others on this list to do a little
digging on other languages they are familiar with.
Hackers with knowledge about socket interfaces in Ruby, Perl, Java and
C# or any other high-level socket mapping, I'd like
answers to the following questions:
* How is the socket addres (or equivalent) abstracted,
what mechanisms are there to make it convenient for
code to handle both IPv4 and IPv6 sockets?
* If there's a high-level semi-automatic DNS interface,
how does that deal with v4 vs v6? Eg, can I ask
"make a TCP connection to www.ripe.net port 80, I don't care
v4 or v6"
* In what way (if any) are the flowinfo and scopeid
parts carried along the with the object doing the
part of struct sockaddr?
