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.
