can_client_access_hack()

bool can_client_access_hack

(

)

Returns TRUE if the client has hack access.

client_kill_server()

void client_kill_server

(

bool

force

)

Kills the server if the client has started it.

If the 'force' parameter is unset, we just do a /quit. If it's set, then we'll send a signal to the server to kill it (use this when the socket is disconnected already).

Forks a server if it can.

is_server_running()

bool is_server_running

(

)

The general chain of events:

Two distinct paths are taken depending on the choice of mode:

if the user selects the multi- player mode, then a packet_req_join_game packet is sent to the server. It is either successful or not. The end.

If the user selects a single- player mode (either a new game or a save game) then:

1. the packet_req_join_game is sent.
2. on receipt, if we can join, then a challenge packet is sent to the server, so we can get hack level control.
3. if we can't get hack, then we get dumped to multi- player mode. If we can, then: a. for a new game, we send a series of packet_generic_message packets with commands to start the game. b. for a saved game, we send the load command with a packet_generic_message, then we send a PACKET_PLAYER_LIST_REQUEST. the response to this request will tell us if the game was loaded or not. if not, then we send another load command. if so, then we send a series of packet_generic_message packets with commands to start the game. Tests if the client has started the server.

send_client_wants_hack()

void send_client_wants_hack

(

const char *

filename

)

If the client is capable of 'wanting hack', then the server will send the client a filename in the packet_join_game_reply packet.

This function creates the file with a suitably random string in it and then sends the string to the server. If the server can open and read the string, then the client is given hack access.
