以下是示例：
[示例开始] .. _dlist_api:
Similar to the single-linked list in many respects, Zephyr includes a double-linked implementation.
-
An empty list has backpointers to itself in the list struct, which can be trivially detected.
-
The head and tail of the list can be detected by comparing the prev/next pointers of a node vs. the list struct address.
.. figure:: dlist-empty.png :align: center :alt: dlist example :figclass: align-center
An empty dlist.
.. doxygengroup:: doubly-linked-list_apis [示例结束]
