* Connectivity driver framework (CDF) list APIs
|
|
*
|
|
* Definitions for CDF Linked Lists API
|
|
*
|
|
* Lists are implemented as a doubly linked list. An item in a list can
|
|
* be of any type as long as the datatype contains a field of type
|
|
* cdf_link_t.
|
|
*
|
|
* In general, a list is a doubly linked list of items with a pointer
|
|
* to the front of the list and a pointer to the end of the list. The
|
|
* list items contain a forward and back link.
|
|
*
|
|
* CDF linked list APIs are NOT thread safe so make sure to use appropriate
|
|
* locking mechanisms to assure operations on the list are thread safe.
