#include <login_server.h>

Detailed Description

This class is the server part of the Login System. It is used in the Front End Service. At the begining, it connects to the WS. When a new player comes in and is authenticated, a callback is called to warn the user code that a new player is here. Example:

void NLNET::CLoginServer::init (  CCallbackServer &  server,
TNewClientCallback  ncl
)  [static]
 

Create the connection to the Welcome Service and install callbacks to the callback server (for a TCP connection) init() will try to find the ListenAddress in the config file and it will be used to say to the client the address to connect to this frontend (using the login system). You can modify this in real time in the config file or with the ls_listen_address command The ListenAddress must be in the form of "itsalive.nevrax.org:38000" (ip+port)
