    8  * A doubly linked list is a data structure consisting of a group of nodes linked together linearly.
    9  * Each node consists of data elements with links to the next node and previous nodes.  The main
   10  * advantage of linked lists (over simple arrays) is the nodes can be inserted and removed
   11  * anywhere in the list without reallocating the entire array. Linked list nodes don't
   12  * need to be stored contiguously in memory, but nodes then you can't access by
   13  * index, you have to be access by traversing the list.
   14  *
   15  * @section dls_createList Creating and Initializing Lists
   16  *
   17  * To create and initialize a linked list the user must create a le_dls_List_t typed list and assign
   18  * LE_DLS_LIST_INIT to it.  The assignment of LE_DLS_LIST_INIT can be done either when the list is
   19  * declared or after its declared.  The list <b>must</b> be initialized before it can be
   20  * used.
   21  *
   22  * @code
   23  * // Create and initialized the list in the declaration.
   24  * le_dls_List_t MyList = LE_DLS_LIST_INIT;
   25  * @endcode
   26  *
   27  * Or
   28  *
   29  * @code
   30  * // Create list.
   31  * le_dls_List_t MyList;
   32  *
   33  * // Initialize the list.
   34  * MyList = LE_DLS_LIST_INIT;
   35  * @endcode
   36  *
   37  * <b> Elements of le_dls_List_t MUST NOT be accessed directly by the user. </b>
   38  *
   39  *
   40  * @section dls_createNode Creating and Accessing Nodes
   41  *
   42  * Nodes can contain any data in any format and is defined and created by the user.  The only
   43  * requirement for nodes is that it must contain a @c le_dls_Link_t link member. The link member must
   44  * be initialized by assigning LE_DLS_LINK_INIT to it before it can be used.  Nodes can then be
   45  * added to the list by passing their links to the add functions (le_dls_Stack(), le_dls_Queue(),
   46  * etc.).  For example:
   47  *
   48  * @code
   49  * // The node may be defined like this.
   50  * typedef struct
   51  * {
   52  *      dataType someUserData;
   53  *      ...
   54  *      le_dls_Link_t myLink;
   55  *
   56  * }
   57  * MyNodeClass_t;
   58  *
   59  * // Create and initialize the list.
   60  * le_dls_List_t MyList = LE_DLS_LIST_INIT;
   61  *
   62  * void foo (void)
   63  * {
   64  *     // Create the node.  Get the memory from a memory pool previously created.
   65  *     MyNodeClass_t* myNodePtr = le_mem_ForceAlloc(MyNodePool);
   66  *
   67  *     // Initialize the node's link.
   68  *     myNodePtr->myLink = LE_DLS_LINK_INIT;
   69  *
   70  *     // Add the node to the head of the list by passing in the node's link.
   71  *     le_dls_Stack(&MyList, &(myNodePtr->myLink));
   72  * }
   73  * @endcode
   74  *
   75  * The links in the nodes are actually added to the list and not the nodes themselves. This
   76  * allows a node to be included on multiple lists through links
   77  * added to different lists. It also allows linking different type nodes in a list.
   78  *
   79  * To obtain the node itself, use the @c CONTAINER_OF macro defined in
   80  * le_basics.h.  Here's a code sample using CONTAINER_OF to obtain the node:
   81  *
   82  * @code
   83  * // Assuming mylist has been created and initialized and is not empty.
   84  * le_dls_Link_t* linkPtr = le_dls_Peek(&MyList);
   85  *
   86  * // Now we have the link but still need the node to access user data.
   87  * // We use CONTAINER_OF to get a pointer to the node given the node's link.
   88  * if (linkPtr != NULL)
   89  * {
   90  *     MyNodeClass_t* myNodePtr = CONTAINER_OF(linkPtr, MyNodeClass_t, myLink);
   91  * }
   92  * @endcode
   93  *
   94  * The user is responsible for creating and freeing memory for all nodes; the linked list module
   95  * only manages the links in the nodes.  The node must be removed from all lists before its
   96  * memory can be freed.
   97  *
   98  * <b>The elements of @c le_dls_Link_t MUST NOT be accessed directly by the user.</b>
   99  *
  100  *
  101  * @section dls_add Adding Links to a List
  102  *
  103  * To add nodes to a list, pass the node's link to one of these functions:
  104  *
  105  * - @c le_dls_Stack() - Adds the link to the head of the list.
  106  * - @c le_dls_Queue() - Adds the link to the tail of the list.
  107  * - @c le_dls_AddAfter() - Adds the link to a list after another specified link.
  108  * - @c le_dls_AddBefore() - Adds the link to a list before another specified link.
  109  *
  110  *
  111  * @section dls_remove Removing Links from a List
  112  *
  113  * To remove nodes from a list, use one of these functions:
  114  *
  115  * - @c le_dls_Pop() - Removes and returns the link at the head of the list.
  116  * - @c le_dls_PopTail() - Removes and returns the link at the tail of the list.
  117  * - @c le_dls_Remove() - Remove a specified link from the list.
  118  *
  119  *
  120  * @section dls_peek Accessing Links in a List
  121  *
  122  * To access a link in a list without removing the link, use one of these functions:
  123  *
  124  * - @c le_dls_Peek() - Returns the link at the head of the list without removing it.
  125  * - @c le_dls_PeekTail() - Returns the link at the tail of the list without removing it.
  126  * - @c le_dls_PeekNext() - Returns the link next to a specified link without removing it.
  127  * - @c le_dls_PeekPrev() - Returns the link previous to a specified link without removing it.
  128  *
  129  *
  130  * @section dls_swap Swapping Links
  131  *
  132  * To swap two links, use:
  133  *
  134  * - @c le_dls_Swap() - Swaps the position of two links in a list.
  135  *
  136  * @section dls_sort Sorting Lists
  137  *
  138  * To sort a list use:
  139  *
  140  * @c le_dls_Sort() - Sorts a list
  141  *
  142  * @section dls_query Querying List Status
  143  *
  144  * These functions can be used to query a list's current status:
  145  *
  146  * - @c le_dls_IsEmpty() - Checks if a given list is empty.
  147  * - @c le_dls_IsInList() - Checks if a specified link is in the list.
  148  * - @c le_dls_IsHead() - Checks if a specified link is at the head of the list.
  149  * - @c le_dls_IsTail() - Checks if a specified link is at the tail of the list.
  150  * - @c le_dls_NumLinks() - Checks the number of links currently in the list.
  151  * - @c le_dls_IsListCorrupted() - Checks if the list is corrupted.
  152  *
  153  *
  154  * @section dls_fifo Queues and Stacks
  155  *
  156  * This implementation of linked lists can be used for either queues or stacks.
  157  *
  158  * To use the list as a queue, restrict additions to the list to @c le_dls_Queue() and removals
  159  * from the list to @c le_dls_Pop().
  160  *
  161  * To use the list as a stack,  restrict additions to the list to @c le_dls_Stack() and removals
  162  * from the list to @c le_dls_Pop().
  163  *
  164  *
  165  * @section dls_synch Thread Safety and Re-Entrancy
  166  *
  167  * All linked list function calls are re-entrant and thread safe themselves, but if the nodes and/or
  168  * list object are shared by multiple threads, explicit steps must be taken to maintain mutual
  169  * exclusion of access. If you're accessing the same list from multiple threads, you @e must use a
  170  * @ref c_mutex "mutex" or some other form of thread synchronization to ensure only one thread
  171  * accesses the list at a time.
