about socket problem

[Yu-Teh Shen]

I got a question about erlang socket.

Now I have a server(written by erlang) and a client(written by C).

Client create a socket connection to server and then idle for a long time.

After that, I kill client process, but I found out that the server didn't
know client was been killed!

And I use netstat -pan in server, the connection is still exist!

Is there anyway, the server can detect client had been killed? Like using
poll function in C socket (error code POLLERR or POLLHUP)

Thanks a lot!
