+/**
+ * Protocol message signature
+ *
+ * A wl_message describes the signature of an actual protocol message, such as a
+ * request or event, that adheres to the Wayland protocol wire format. The
+ * protocol implementation uses a wl_message within its demarshal machinery for
+ * decoding messages between a compositor and its clients. In a sense, a
+ * wl_message is to a protocol message like a class is to an object.
+ *
+ * The `name` of a wl_message is the name of the corresponding protocol message.
+ *
+ * The `signature` is an ordered list of symbols representing the data types
+ * of message arguments and, optionally, a protocol version and indicators for
+ * nullability. A leading integer in the `signature` indicates the _since_
+ * version of the protocol message. A `?` preceding a data type symbol indicates
+ * that the following argument type is nullable. While it is a protocol violation
+ * to send messages with non-nullable arguments set to `NULL`, event handlers in
+ * clients might still get called with non-nullable object arguments set to
+ * `NULL`. This can happen when the client destroyed the object being used as
+ * argument on its side and an event referencing that object was sent before the
+ * server knew about its destruction. As this race cannot be prevented, clients
+ * should - as a general rule - program their event handlers such that they can
+ * handle object arguments declared non-nullable being `NULL` gracefully.
+ *
+ * When no arguments accompany a message, `signature` is an empty string.
+ *
+ * Symbols:
+ *
+ * * `i`: int
+ * * `u`: uint
+ * * `f`: fixed
+ * * `s`: string
+ * * `o`: object
+ * * `n`: new_id
+ * * `a`: array
+ * * `h`: fd
+ * * `?`: following argument is nullable
+ *
+ * While demarshaling primitive arguments is straightforward, when demarshaling
+ * messages containing `object` or `new_id` arguments, the protocol
+ * implementation often must determine the type of the object. The `types` of a
+ * wl_message is an array of wl_interface references that correspond to `o` and
+ * `n` arguments in `signature`, with `NULL` placeholders for arguments with
+ * non-object types.
+ *
+ * Consider the protocol event wl_display `delete_id` that has a single `uint`
+ * argument. The wl_message is:
+ *
+ * \code
+ * { "delete_id", "u", [NULL] }
+ * \endcode
+ *
+ * Here, the message `name` is `"delete_id"`, the `signature` is `"u"`, and the
+ * argument `types` is `[NULL]`, indicating that the `uint` argument has no
+ * corresponding wl_interface since it is a primitive argument.
+ *
+ * In contrast, consider a `wl_foo` interface supporting protocol request `bar`
+ * that has existed since version 2, and has two arguments: a `uint` and an
+ * object of type `wl_baz_interface` that may be `NULL`. Such a `wl_message`
+ * might be:
+ *
+ * \code
+ * { "bar", "2u?o", [NULL, &wl_baz_interface] }
+ * \endcode
+ *
+ * Here, the message `name` is `"bar"`, and the `signature` is `"2u?o"`. Notice
+ * how the `2` indicates the protocol version, the `u` indicates the first
+ * argument type is `uint`, and the `?o` indicates that the second argument
+ * is an object that may be `NULL`. Lastly, the argument `types` array indicates
+ * that no wl_interface corresponds to the first argument, while the type
+ * `wl_baz_interface` corresponds to the second argument.

+/**
+ * Protocol object interface
+ *
+ * A wl_interface describes the API of a protocol object defined in the Wayland
+ * protocol specification. The protocol implementation uses a wl_interface
+ * within its marshalling machinery for encoding client requests.
+ *
+ * The `name` of a wl_interface is the name of the corresponding protocol
+ * interface, and `version` represents the version of the interface. The members
+ * `method_count` and `event_count` represent the number of `methods` (requests)
+ * and `events` in the respective wl_message members.
+ *
+ * For example, consider a protocol interface `foo`, marked as version `1`, with
+ * two requests and one event.
+ *
+ * \code
+ *
+ *
+ *
+ *
+ *
+ * \endcode
+ *
+ * Given two wl_message arrays `foo_requests` and `foo_events`, a wl_interface
+ * for `foo` might be:
+ *
+ * \code
+ * struct wl_interface foo_interface = {
+ * "foo", 1,
+ * 2, foo_requests,
+ * 1, foo_events
+ * };
+ * \endcode
+ *
+ * \note The server side of the protocol may define interface implementation
+ * types that incorporate the term `interface` in their name. Take
+ * care to not confuse these server-side `struct`s with a wl_interface
+ * variable whose name also ends in `interface`. For example, while the
+ * server may define a type `struct wl_foo_interface`, the client may
+ * define a `struct wl_interface wl_foo_interface`.

+/** \class wl_list
+ *
+ * \brief Doubly-linked list
+ *
+ * On its own, an instance of `struct wl_list` represents the sentinel head of
+ * a doubly-linked list, and must be initialized using wl_list_init().
+ * When empty, the list head's `next` and `prev` members point to the list head
+ * itself, otherwise `next` references the first element in the list, and `prev`
+ * refers to the last element in the list.
+ *
+ * Use the `struct wl_list` type to represent both the list head and the links
+ * between elements within the list. Use wl_list_empty() to determine if the
+ * list is empty in O(1).
+ *
+ * All elements in the list must be of the same type. The element type must have
+ * a `struct wl_list` member, often named `link` by convention. Prior to
+ * insertion, there is no need to initialize an element's `link` - invoking
+ * wl_list_init() on an individual list element's `struct wl_list` member is
+ * unnecessary if the very next operation is wl_list_insert(). However, a
+ * common idiom is to initialize an element's `link` prior to removal - ensure
+ * safety by invoking wl_list_init() before wl_list_remove().
+ *
+ * Consider a list reference `struct wl_list foo_list`, an element type as
+ * `struct element`, and an element's link member as `struct wl_list link`.
+ *
+ * The following code initializes a list and adds three elements to it.
+ *
+ * \code
+ * struct wl_list foo_list;
+ *
+ * struct element {
+ * int foo;
+ * struct wl_list link;
+ * };
+ * struct element e1, e2, e3;
+ *
+ * wl_list_init(&foo_list);
+ * wl_list_insert(&foo_list, &e1.link); // e1 is the first element
+ * wl_list_insert(&foo_list, &e2.link); // e2 is now the first element
+ * wl_list_insert(&e2.link, &e3.link); // insert e3 after e2
+ * \endcode
+ *
+ * The list now looks like [e2, e3, e1].
+ *
+ * The `wl_list` API provides some iterator macros. For example, to iterate
+ * a list in ascending order:
+ *
+ * \code
+ * struct element *e;
+ * wl_list_for_each(e, foo_list, link) {
+ * do_something_with_element(e);
+ * }
+ * \endcode
+ *
+ * See the documentation of each iterator for details.

+ * dispatchers provide a way to abstract the function calling process to be
+ * friendlier to other function calling systems.
+ *
+ * A dispatcher takes five arguments: The first is the dispatcher-specific
+ * implementation associated with the target object. The second is the object
+ * upon which the callback is being invoked (either wl_proxy or wl_resource).
+ * The third and fourth arguments are the opcode and the wl_message
+ * corresponding to the callback. The final argument is an array of arguments
+ * received from the other process via the wire protocol.
