2 | * Family 0x0013 - Server-Side/Stored Information. |
---|
3 | * |
---|
4 | * Relatively new facility that allows certain types of information, such as |
---|
5 | * a user's buddy list, permit/deny list, and permit/deny preferences, to be |
---|
6 | * stored on the server, so that they can be accessed from any client. |
---|
7 | * |
---|
8 | * We keep 2 copies of SSI data: |
---|
9 | * 1) An exact copy of what is stored on the AIM servers. |
---|
10 | * 2) A local copy that we make changes to, and then send diffs |
---|
11 | * between this and the exact copy to keep them in sync. |
---|
12 | * |
---|
13 | * All the "aim_ssi_itemlist_bleh" functions near the top just modify the list |
---|
14 | * that is given to them (i.e. they don't send SNACs). |
---|
15 | * |
---|
16 | * The SNAC sending and receiving functions are lower down in the file, and |
---|
17 | * they're simpler. They are in the order of the subtypes they deal with, |
---|
18 | * starting with the request rights function (subtype 0x0002), then parse |
---|
19 | * rights (subtype 0x0003), then--well, you get the idea. |
---|
20 | * |
---|
21 | * This is entirely too complicated. |
---|
22 | * You don't know the half of it. |
