---|
| 364 | * The problem - I'm not sure where to hook into the owl/faim |
---|
| 365 | * interface to keep track of when the AIM socket(s) open and |
---|
| 366 | * close. In particular, the bosconn thing throws me off. So, |
---|
| 367 | * rather than register particular dispatchers for AIM, I look up |
---|
| 368 | * the relevant FDs and add them to select's watch lists, then |
---|
| 369 | * check for them individually before moving on to the other |
---|
| 370 | * dispatchers. --asedeno |
