Could you post a more complete list of what you think a user interface to TCP
should include ?

As for your request on 'YOURCONNECTISBOGUS', I think you can arrange something
like that on BSD. (I don't know whether you're talking about BSD or Sys-V).
If you are interested, look in the manual entries for socket(2),
setsocketopt(2) - look for the SO_KEEPALIVE option.
I'm not sure if you can detect dead connections with select(2), or maybe

If you find a way, please post it. I'm sure lots of people are interested.
