7.9.3 Example: Interface on Server
On the server side, the KVC protocol is represented by two classes:
CKVCServer and CKVCConnection. An object of the CKVCServer class
represents the actual server (the "listener") and an object of the
CKVCConnection class represents a connection to a client.
"Server class"
class CKVCServer {
public:
virtual int Init();
virtual int Exit();
virtual CKVCConnection* OnClientConnect(SOCKET socket,
sockaddr_in
&sockAdr);
virtual int OnClientDisconnect(CKVCConnection *pConnection,
TDisconInfo info);
POSITION ConnectionListHeadPos();
CKVCConnection* ConnectionListGetNext(POSITION pos);
int ConnectionListGetCount();
};
int Init();
Initalizes the server and opens the port 0xCEBA for
incoming connections.
int Exit();
Finishes all connections and closes the port 0xCEBA.
