static void DistributeQueue ( CommandQueue queue,

"Send" a particular CommandQueue to all clients.

Parameters:
queue The queue of commands that has to be distributed.
owner The client that owns the commands,

void NetworkSendCommand ( TileIndex  tile,
uint32  p1,
uint32  p2,
uint32  cmd,
CommandCallback callback,
const char *  text,
CompanyID  company 
)

Prepare a DoCommand to be send over the network.

Parameters:
tile The tile to perform a command on (see CommandProc)
p1 Additional data for the command (see CommandProc)
p2 Additional data for the command (see CommandProc)
cmd The command to execute (a CMD_* value)
callback A callback function to call after the command is finished
text The text to pass
company The company that wants to send the command

void NetworkSyncCommandQueue ( NetworkClientSocket *  cs  ) 

Sync our local command queue to the command queue of the given socket.

This is needed for the case where we receive a command before saving the game for a joining client, but without the execution of those commands. Not syncing those commands means that the client will never get them and as such will be in a desynced state from the time it started with joining.

Parameters:
cs The client to sync the queue to.
