Member Function Documentation

◆ CloseConnection()

NetworkRecvStatus ClientNetworkStunSocketHandler::CloseConnection ( bool error = true )

overridevirtual

This will put this socket handler in a close state.

It will not actually close the OS socket; use CloseSocket for this.

Parameters

error Whether we quit under an error condition or not.

Returns: new status of the connection.

Reimplemented from NetworkTCPSocketHandler.

Definition at line 99 of file network_stun.cpp.

References NetworkTCPSocketHandler::CloseConnection(), connecter, error(), TCPConnecter::Kill(), and NETWORK_RECV_STATUS_OKAY.

◆ Connect()

void ClientNetworkStunSocketHandler::Connect	(	const std::string &	token,
		uint8	family
	)

Connect to the STUN server over either IPv4 or IPv6.

Parameters

token	The token as received from the Game Coordinator.
family	What IP family to use.

Definition at line 69 of file network_stun.cpp.

References connecter, family, NetworkStunConnectionString(), and token.

◆ Stun()

std::unique_ptr< ClientNetworkStunSocketHandler > ClientNetworkStunSocketHandler::Stun	(	const std::string &	token,
		uint8	family
	)

static

Send a STUN packet to the STUN server.

Parameters

token	The token as received from the Game Coordinator.
family	What IP family this STUN request is for.

Returns: The handler for this STUN request.

Definition at line 83 of file network_stun.cpp.
