|
* Channel user factory. |
360 |
|
|
* |
361 |
|
|
* Inputs: |
362 |
|
|
* - channel that the user should belong to |
363 |
|
|
* - nick/UID with any appropriate prefixes (e.g. ~, &, @, %, +) |
364 |
|
|
* (if the user has a UID it must be used) |
365 |
|
|
* |
366 |
|
|
* Outputs: |
367 |
|
|
* - on success, a new channel user object |
368 |
|
|
* - on failure (NULL channel, or user kicked by channel_join hook), NULL |
369 |
|
|
* |
370 |
|
|
* Side Effects: |
371 |
|
|
* - the channel user object is automatically associated to its parents |
372 |
|
|
* - channel_join hook is called |

* Rewritten 06/23/05 by nenolod: |
377 |
|
|
* |
378 |
|
|
* Iterate through the list of prefix characters we know about. |
379 |
|
|
* Continue to do so until all prefixes are covered. Then add the |
380 |
|
|
* nick to the channel, with the privs he has acquired thus far. |

382 |
|
|
* Once, and only once we have done that do we start in on checking |
383 |
|
|
* privileges. Otherwise we have a very inefficient way of doing |
384 |
|
|
* things. It worked fine for shrike, but the old code was restricted |
385 |
|
|
* to handling only @, @+ and + as prefixes. |
