how to close listening socket once TCP connection has been accepted

[Anatoly Karp]

Hello all,

I am writing a single-threaded server in Cache and I want to
prevent any further TCP connections to my port once I have accepted
the first connection. [Note that TCP stack accepts new connections
even though the main thread makes no attempt to communicate over
those new connections - thus the client may take unduly long time
to discover that nobody is talking with them].

With the traditional Berekeley socket API
this would've been easy due to the distinction between the
listening and connected sockets (so I could just close
the listening socket immediately after return of accept()).
With Cache I have so far not found any way to achieve this
effect. Any ideas?

thanks,
