游戏《家园》源码

// TMsgAuth1LoginHW.h

// AuthServer messages implementing the Auth1 Family login protocol.
// This header/source implements messages:
//	Auth1LoginRequest
//	Auth1NewLoginRequest
// It also includes the Auth1LoginReply which is implemented in its own header
// and source module (it is shared).

// Auth1LoginRequest begins login for an existing user and is sent from the Client to
// the AuthServer.

// Auth1NewLoginRequest begins login for a new user and is sent from the Client to
// the AuthServer.

// Auth1LoginReply is sent in response to both Auth1LoginRequest and
// Auth1NewLoginRequest from the AuthServer to the client and completes the login.
