Detailed Description

Socket server bas class, that opens a port and accepts connection until no more client handles. Each client are given a welcome message - if such is defined. When client messages are received (in a receive thread) the butes are transferred in a call to gotNewMessage(), and are assumed consumed here. Transmissions to the client are performed by a call to sendBlock().

bool USockServ::blockSend	(	int	client,
		const char *	buffer,
		int	length,
		int	msTimeout
	)

Send data to client. if connection to client is open the data is send. returns false if client do not exist or data could not be send within timeout period.

int USockServ::getFreeClientHandle ( )

protectedvirtual

Get free handle to a client connection. Returns -1 if no handle is available.

int USockServ::getUsedClientHandles ( )

virtual

Get count of used handles.

int USockServ::handleConnection	(	int	iConn,
		struct sockaddr_in	iConnInfo
	)

protectedvirtual

Handle connection for client number clnt. clnt is index to client handle.

bool USockServ::isActive ( int client )

Tests if there is an active connection for this client, returns true if client is active (connected).

References USockServConnection::client, and MAX_CLIENTS_SERVED.

bool USockServ::isRunning ( )

inline

Is server running. Returns false if server is not accepting connections.

References USockServConnection::handleConnection(), USockServConnection::info(), and USockServConnection::justConnected().

bool USockServ::justConnected ( int client )

protectedvirtual

tests wether a newly accepted connection can be accepted, and initiates any queues etc. that needs to be set up for the connection. Returns true if connection is acceptable.

int USockServ::runServerThread ( )

int USockServ::setPort ( int iPort )
