2 | * Family 0x0004 - Routines for sending/receiving Instant Messages. |
---|
3 | * |
---|
4 | * Note the term ICBM (Inter-Client Basic Message) which blankets |
---|
5 | * all types of genericly routed through-server messages. Within |
---|
6 | * the ICBM types (family 4), a channel is defined. Each channel |
---|
7 | * represents a different type of message. Channel 1 is used for |
---|
8 | * what would commonly be called an "instant message". Channel 2 |
---|
9 | * is used for negotiating "rendezvous". These transactions end in |
---|
10 | * something more complex happening, such as a chat invitation, or |
---|
11 | * a file transfer. Channel 3 is used for chat messages (not in |
---|
12 | * the same family as these channels). Channel 4 is used for |
---|
13 | * various ICQ messages. Examples are normal messages, URLs, and |
---|
14 | * old-style authorization. |
---|
15 | * |
---|
16 | * In addition to the channel, every ICBM contains a cookie. For |
---|
17 | * standard IMs, these are only used for error messages. However, |
---|
18 | * the more complex rendezvous messages make suitably more complex |
---|
19 | * use of this field. |
---|
20 | * |
---|
21 | * TODO: Split this up into an im.c file an an icbm.c file. It |
---|
22 | * will be beautiful, you'll see. |
---|
23 | * |
---|
24 | * Need to rename all the mpmsg messages to aim_im_bleh. |
---|
25 | * |
---|
26 | * Make sure aim_conn_findbygroup is used by all functions. |

202 | * AIM_IMFLAGS_OFFLINE--If destination is offline, store it until they are |

203 | * online (probably ICQ only). |
---|
204 | * AIM_IMFLAGS_UNICODE--Instead of ASCII7, the passed message is |
---|
205 | * made up of UNICODE duples. If you set |
---|
206 | * this, you'd better be damn sure you know |
---|
207 | * what you're doing. |
---|
208 | * AIM_IMFLAGS_ISO_8859_1 -- The message contains the ASCII8 subset |
---|
209 | * known as ISO-8859-1. |
---|
210 | * |
---|
211 | * Generally, you should use the lowest encoding possible to send |
---|
212 | * your message. If you only use basic punctuation and the generic |
---|
213 | * Latin alphabet, use ASCII7 (no flags). If you happen to use non-ASCII7 |
---|
214 | * characters, but they are all clearly defined in ISO-8859-1, then |
---|
215 | * use that. Keep in mind that not all characters in the PC ASCII8 |
---|
216 | * character set are defined in the ISO standard. For those cases (most |
---|
217 | * notably when the (r) symbol is used), you must use the full UNICODE |
---|
218 | * encoding for your message. In UNICODE mode, _all_ characters must |
---|
219 | * occupy 16bits, including ones that are not special. (Remember that |
---|
220 | * the first 128 UNICODE symbols are equivelent to ASCII7, however they |
---|
221 | * must be prefixed with a zero high order byte.) |
---|
222 | * |
---|
223 | * I strongly discourage the use of UNICODE mode, mainly because none |
---|
224 | * of the clients I use can parse those messages (and besides that, |
---|
225 | * wchars are difficult and non-portable to handle in most UNIX environments). |
---|
226 | * If you really need to include special characters, use the HTML UNICODE |
---|
227 | * entities. These are of the form ߪ where 2026 is the hex |
---|
228 | * representation of the UNICODE index (in this case, UNICODE |

229 | * "Horizontal Ellipsis", or 133 in in ASCII8). |

---|
234 | * supposed to be layed out. Most obviously, tlvlists should be used |
---|
235 | * instead of writing out the bytes manually. |

1073 | * Ahh, the joys of nearly ridiculous over-engineering. |
---|
1074 | * |
---|
1075 | * Not only do AIM ICBM's support multiple channels. Not only do they |
---|
1076 | * support multiple character sets. But they support multiple character |
---|
1077 | * sets / encodings within the same ICBM. |
---|
1078 | * |
---|
1079 | * These multipart messages allow for complex space savings techniques, which |
---|
1080 | * seem utterly unnecessary by today's standards. In fact, there is only |
---|
1081 | * one client still in popular use that still uses this method: AOL for the |
---|
1082 | * Macintosh, Version 5.0. Obscure, yes, I know. |
---|
1083 | * |
---|
1084 | * In modern (non-"legacy") clients, if the user tries to send a character |
---|
1085 | * that is not ISO-8859-1 or ASCII, the client will send the entire message |
---|
1086 | * as UNICODE, meaning that every character in the message will occupy the |
---|
1087 | * full 16 bit UNICODE field, even if the high order byte would be zero. |
---|
1088 | * Multipart messages prevent this wasted space by allowing the client to |
---|
1089 | * only send the characters in UNICODE that need to be sent that way, and |
---|
1090 | * the rest of the message can be sent in whatever the native character |
---|
1091 | * set is (probably ASCII). |
---|
1092 | * |
---|
1093 | * An important note is that sections will be displayed in the order that |
---|
1094 | * they appear in the ICBM. There is no facility for merging or rearranging |
---|
1095 | * sections at run time. So if you have, say, ASCII then UNICODE then ASCII, |
---|
1096 | * you must supply two ASCII sections with a UNICODE in the middle, and incur |
---|
1097 | * the associated overhead. |
---|
1098 | * |
---|
1099 | * Normally I would have laughed and given a firm 'no' to supporting this |
---|
1100 | * seldom-used feature, but something is attracting me to it. In the future, |
---|
1101 | * it may be possible to abuse this to send mixed-media messages to other |
---|
1102 | * open source clients (like encryption or something) -- see faimtest for |
---|
1103 | * examples of how to do this. |
---|
1104 | * |
---|
1105 | * I would definitly recommend avoiding this feature unless you really |
---|
1106 | * know what you are doing, and/or you have something neat to do with it. |
