68	* This file defines five types of data structures: singly-linked lists,
69	* lists, simple queues, tail queues, and circular queues.
70	*
71	*
72	* A singly-linked list is headed by a single forward pointer. The elements
73	* are singly linked for minimum space and pointer manipulation overhead at
74	* the expense of O(n) removal for arbitrary elements. New elements can be
75	* added to the list after an existing element or at the head of the list.
76	* Elements being removed from the head of the list should use the explicit
77	* macro for this purpose for optimum efficiency. A singly-linked list may
78	* only be traversed in the forward direction. Singly-linked lists are ideal
79	* for applications with large datasets and few or no removals or for
80	* implementing a LIFO queue.
81	*
82	* A list is headed by a single forward pointer (or an array of forward
83	* pointers for a hash table header). The elements are doubly linked
84	* so that an arbitrary element can be removed without a need to
85	* traverse the list. New elements can be added to the list before
86	* or after an existing element or at the head of the list. A list
87	* may only be traversed in the forward direction.
88	*
89	* A simple queue is headed by a pair of pointers, one the head of the
90	* list and the other to the tail of the list. The elements are singly
91	* linked to save space, so elements can only be removed from the
92	* head of the list. New elements can be added to the list before or after
93	* an existing element, at the head of the list, or at the end of the
94	* list. A simple queue may only be traversed in the forward direction.
95	*
96	* A tail queue is headed by a pair of pointers, one to the head of the
97	* list and the other to the tail of the list. The elements are doubly
98	* linked so that an arbitrary element can be removed without a need to
99	* traverse the list. New elements can be added to the list before or
100	* after an existing element, at the head of the list, or at the end of
101	* the list. A tail queue may be traversed in either direction.
102	*
103	* A circle queue is headed by a pair of pointers, one to the head of the
104	* list and the other to the tail of the list. The elements are doubly
105	* linked so that an arbitrary element can be removed without a need to
106	* traverse the list. New elements can be added to the list before or after
107	* an existing element, at the head of the list, or at the end of the list.
108	* A circle queue may be traversed in either direction, but has a more
109	* complex end of list detection.
110	*
111	* For details on the use of these macros, see the queue(3) manual page.

4443	* In OPC UA, all communication is based on service calls, each consisting of a
4444	* request and a response message. These messages are defined as data structures
4445	* with a binary encoding and listed in :ref:`generated-types`. Since all
4446	* Services are pre-defined in the standard, they cannot be modified by the
4447	* user. But you can use the :ref:`Call <method-services>` service to invoke
4448	* user-defined methods on the server.
4449	*
4450	* The following service signatures are internal and *not visible to users*.
4451	* Still, we present them here for an overview of the capabilities of OPC UA.
4452	* Please refer to the :ref:`client` and :ref:`server` API where the services
4453	* are exposed to end users. Please see part 4 of the OPC UA standard for the
4454	* authoritative definition of the service and their behaviour.
4455	*
4456	* Most services take as input the server, the current session and pointers to
4457	* the request and response structures. Possible error codes are returned as
4458	* part of the response. */

7275	* Type Encoding and Decoding
7276	* --------------------------
7277	* The following methods contain encoding and decoding functions for the builtin
7278	* data types and generic functions that operate on all types and arrays. This
7279	* requires the type description from a UA_DataType structure.
7280	*
7281	* Breaking a message up into chunks is integrated with the encoding. When the
7282	* end of a buffer is reached, a callback is executed that sends the current
7283	* buffer as a chunk and exchanges the encoding buffer "underneath" the ongoing
7284	* encoding. This reduces the RAM requirements and unnecessary copying. */
