void	MarkClosed ()
	Mark the connection as closed.
bool	HasClientQuit () const
	Whether the current client connected to the socket has quit.
void	Reopen ()
	Reopen the socket so we can send/receive stuff again.

Constructor & Destructor Documentation

NetworkStunSocketHandler()

NetworkStunSocketHandler::NetworkStunSocketHandler ( SOCKET  s = INVALID_SOCKET )

inline

Create a new cs socket handler for a given cs.

Parameters

s	the socket we are connected with.
address	IP etc. of the client.

Definition at line 50 of file tcp_stun.h.

Member Function Documentation

Receive_SERCLI_STUN()

bool NetworkStunSocketHandler::Receive_SERCLI_STUN ( Packet &  p )

protectedvirtual

Send a STUN request to the STUN server letting the Game Coordinator know what our actually public IP:port is.

uint8_t Game Coordinator protocol version. string Token to track the current STUN request. uint8_t Which interface number this is (for example, IPv4 or IPv6). The Game Coordinator relays this number back in later packets.

Parameters

p	The packet that was just received.

Returns

True upon success, otherwise false.

ReceiveInvalidPacket()

bool NetworkStunSocketHandler::ReceiveInvalidPacket ( PacketStunType  type )

protected

Helper for logging receiving invalid packets.

Parameters

type	The received packet type.

Returns

Always false, as it's an error.
