of_fd fs fd returns a server configured to accept connections on listening socket fd.

listen fs proto address callback listens on the address address and prepares to serve 9P via the callback. The proto and address can be either:

• unix /path/to/socket
• tcp ip:port

shutdown t requests that the running server t is shutdown, and blocks until the shutdown is complete and resources are freed.

serve_forever t starts serving 9P requests via t. This thread only returns when the server has been shutdown.
