| IQUEUEs |
| This file contains functions that helps to manage task queues. |
| These functions are different from the functions that manages the |
| QUEUE and QQUEUE types. In particular, these functions no more relies |
| on the prev & next fields of the task descriptor. In that way, tasks |
| can be inserted in more than one queue at a time. |
| Basically, an IQUEUE has an "I"nternal prev/next structure, that may |
| be shared between one or more queue. Of course, the user MUST |
| guarantee that the same task will not be inserted in two IQUEUEs that |
| share the same prev/next buffer. |
| The queue insertion is made by the following functions: |
| iq_insert -> insertion based on the priority field. |
| iq_timespec_insert -> same as above but use the timespec_priority field |
| iq_insertfirst -> insert in the first position of the queue |
