2 | * Server-Side/Stored Information. |
---|
3 | * |
---|
4 | * Relatively new facility that allows storing of certain types of information, |
---|
5 | * such as a users buddy list, permit/deny list, and permit/deny preferences, |
---|
6 | * to be stored on the server, so that they can be accessed from any client. |
---|
7 | * |
---|
8 | * We keep a copy of the ssi data in sess->ssi, because the data needs to be |
---|
9 | * accessed for various reasons. So all the "aim_ssi_itemlist_bleh" functions |
---|
10 | * near the top just manage the local data. |
---|
11 | * |
---|
12 | * The SNAC sending and receiving functions are lower down in the file, and |
---|
13 | * they're simpler. They are in the order of the subtypes they deal with, |
---|
14 | * starting with the request rights function (subtype 0x0002), then parse |
---|
15 | * rights (subtype 0x0003), then--well, you get the idea. |
---|
16 | * |
---|
17 | * This is entirely too complicated. |
---|
18 | * You don't know the half of it. |
---|
19 | * |
---|
20 | * XXX - Test for memory leaks |
---|
21 | * XXX - Better parsing of rights, and use the rights info to limit adds |
