◆ get_lanserver_announcement()

void get_lanserver_announcement ( )

Listen for UDP packets multicasted from clients requesting announcement of servers on the LAN.

Definition at line 572 of file sernet.cpp.

Referenced by freeciv::server::pulse().

◆ handle_client_heartbeat()

void handle_client_heartbeat ( struct connection * pconn )

Handle client's regular hearbeat.

Definition at line 563 of file sernet.cpp.

◆ handle_conn_pong()

void handle_conn_pong ( struct connection * pconn )

Handle response to ping.

Definition at line 541 of file sernet.cpp.

Referenced by server_packet_input().

◆ incoming_client_packets()

void incoming_client_packets ( struct connection * pconn )

Handle all incoming packets on a client connection.

Precondition - we have read_socket_data. Postcondition - there are no more packets to handle on this connection.

Definition at line 229 of file sernet.cpp.

Referenced by freeciv::server::input_on_socket().

◆ init_connections()

void init_connections ( )

Initialize connection related stuff.

Attention: Logging is not available within this functions!

Definition at line 452 of file sernet.cpp.

Referenced by main().

◆ really_close_connections()

void really_close_connections ( )

Now really close connections marked as 'is_closing'.

Do this here to avoid recursive sending.

Definition at line 140 of file sernet.cpp.

◆ server_make_connection()

int server_make_connection	(	QIODevice *	new_sock,
		const QString &	client_addr,
		const QString &	ip_addr
	)

Server accepts connection from client: Low level socket stuff, and basic-initialize the connection struct.

Returns 0 on success, -1 on failure (bad accept(), or too many connections).

Definition at line 310 of file sernet.cpp.

Referenced by freeciv::server::accept_local_connections(), and freeciv::server::accept_tcp_connections().

◆ server_open_socket()

std::optional<socket_server> server_open_socket ( )

Open server socket to be used to accept client connections and open a server socket for server LAN announcements.
