CLASS ServerStream
ServerStream implementes a Daemon which accepts stream connections over sockets, and forks into a child process to handle them.
To implement a daemon, derive from
ServerStream<SocketStream, SERVER_LISTEN_PORT>
The type SocketStream specifies that incoming connections should be treated as normal sockets, and SERVER_LISTEN_PORT is the port to listen to (if it's a inet socket, and if not overridden in the config file). The actual addresses (or names) to bind to are specified in the configuration file by the user.
Make sure SERVERSTREAM_VERIFY_SERVER_KEYS(0) is included in the configuration verification structure in the "Server" sub configuration. 0 could be replaced with a default address, for example "unix:/var/run/server.sock" to specific a default UNIX socket in the filesystem.
See test/basicserver for a simple example.
The ListenAddresses key in the Server subconfiguration is a comma separated list of addresses, specified as family:name. Internet sockets are family 'inet', for example 'inet:localhost' (or 'inet:localhost:1080' to specify a port number as well), and unix domain sockets are 'unix', example above.
Override Connection to handle the connection.
Remember to override Daemon functions like the server name, and start it up, just like a generic Daemon.
FUNCTION ServerStream::Connection
This function takes a connected stream as it's argument. It should then proceed to do whatever it needs to do to talk to the client.
Using IOStreamGetLine or a Protocol class to communicate may be quick ways of implementing this functionality.
