* This file implements all of the goo on the server side for handling |
31 |
|
|
* clients. It's got a bunch of global variables for keeping track of |
32 |
|
|
* each of the clients. |
33 |
|
|
* |
34 |
|
|
* Note: All functions that are used to process data from the client |
35 |
|
|
* have the prototype of (char *data, int datalen, int client_num). This |
36 |
|
|
* way, we can use one dispatch table. |
37 |
|
|
* |
38 |
|
|
* esrv_map_new starts updating the map |
39 |
|
|
* |
40 |
|
|
* esrv_map_setbelow allows filling in all of the faces for the map. |
41 |
|
|
* if a face has not already been sent to the client, it is sent now. |
42 |
|
|
* |
43 |
|
|
* mapcellchanged, compactlayer, compactstack, perform the map compressing |
44 |
|

* operations |
