|
* This is the list implementation used by the scheduler. While it is tailored
|
|
* heavily for the schedulers needs, it is also available for use by
|
|
* application code.
|
|
*
|
|
* list_ts can only store pointers to list_item_ts. Each ListItem_t contains a
|
|
* numeric value (xItemValue). Most of the time the lists are sorted in
|
|
* ascending item value order.
|
|
*
|
|
* Lists are created already containing one list item. The value of this
|
|
* item is the maximum possible that can be stored, it is therefore always at
|
|
* the end of the list and acts as a marker. The list member pxHead always
|
|
* points to this marker - even though it is at the tail of the list. This
|
|
* is because the tail contains a wrap back pointer to the true head of
|
|
* the list.
|
|
*
|
|
* In addition to it's value, each list item contains a pointer to the next
|
|
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
|
|
* and a pointer to back to the object that contains it. These later two
|
|
* pointers are included for efficiency of list manipulation. There is
|
|
* effectively a two way link between the object containing the list item and
|
|
* the list item itself.
