## Function Documentation

DEF_SERVER_RECEIVE_COMMAND | ( | PACKET_CLIENT_COMMAND |  | ) |

The client has done a command and wants us to handle it.

Parameters:

  | *cs | the connected client that has sent the command
  | *p | the packet in which the command was sent

Only CMD_COMPANY_CTRL is always allowed, for the rest, playas needs to match the company in the packet. If it doesn't, the client has done something pretty naughty (or a bug), and will be kicked

Todo:
  CMD_COMPANY_CTRL with p1 = 0 announces a new company to the server. To give the company the correct ID, the server injects p2 and executes the command. Any other p1 is prohibited. Pretty ugly and should be redone together with its function.

  CmdCompanyCtrl()

bool NetworkServerChangeClientName | ( | ClientID | client_id,
|  | const char * | new_name |
| ) |  |  |

Change the client name of the given client.

Parameters:

  | client_id | the client to change the name of
  | new_name | the new name for the client

Returns:
  true iff the name was changed

void NetworkServerDoMove | ( | ClientID | client_id,
|  | CompanyID | company_id |
| ) |  |  |

Handle the tid-bits of moving a client from one company to another.

Parameters:

  | client_id | id of the client we want to move.
  | company_id | id of the company we want to move the client to.

Returns:
  void
