-/** @file

-    This extension defines an interface that can be used in LV2 plugins and

-    hosts to create UIs for plugins. The UIs are plugins that reside in

-    shared object files in an LV2 bundle and are referenced in the RDF data

-    using the triples (Turtle shown)

-<pre>    

-    @@prefix uiext: <http://lv2plug.in/ns/extensions/ui#> .

-    <http://my.plugin>    uiext:ui     <http://my.pluginui> .

-    <http://my.plugin>    a            uiext:GtkUI .

-    <http://my.pluginui>  uiext:binary <myui.so> .

-</pre>

-    where <http://my.plugin> is the URI of the plugin, <http://my.pluginui> is

-    the URI of the plugin UI and <myui.so> is the relative URI to the shared 

-    object file. While it is possible to have the plugin UI and the plugin in 

-    the same shared object file it is probably a good idea to keep them 

-    separate so that hosts that don't want UIs don't have to load the UI code.

-    A UI MUST specify its class in the RDF data, in this case uiext:GtkUI. The

-    class defines what type the UI is, e.g. what graphics toolkit it uses.

-    There are no UI classes defined in this extension, those are specified

-    separately (and anyone can define their own).

-    

-    (Note: the prefix above is used throughout this file for the same URI)

-    

-    It's entirely possible to have multiple UIs for the same plugin, or to have

-    the UI for a plugin in a different bundle from the actual plugin - this

-    way people other than the plugin author can write plugin UIs independently

-    without editing the original plugin bundle.

-    

-    Note that the process that loads the shared object file containing the UI

-    code and the process that loads the shared object file containing the 

-    actual plugin implementation does not have to be the same. There are many

-    valid reasons for having the plugin and the UI in different processes, or

-    even on different machines. This means that you can _not_ use singletons

-    and global variables and expect them to refer to the same objects in the

-    UI and the actual plugin. The function callback interface defined in this

-    header is all you can expect to work.

-    

-    Since the LV2 specification itself allows for extensions that may add 

-    new types of data and configuration parameters that plugin authors may 

-    want to control with a UI, this extension allows for meta-extensions that

-    can extend the interface between the UI and the host. These extensions

-    mirror the extensions used for plugins - there are required and optional

-    "features" that you declare in the RDF data for the UI as

-<pre>    

-    <http://my.pluginui> uiext:requiredFeature <http://my.feature> .

-    <http://my.pluginui> uiext:optionalFeature <http://my.feature> .

-</pre>

-    These predicates have the same semantics as lv2:requiredFeature and 

-    lv2:optionalFeature - if a UI is declaring a feature as required, the

-    host is NOT allowed to load it unless it supports that feature, and if it

-    does support a feature (required or optional) it MUST pass that feature's

-    URI and any additional data (specified by the meta-extension that defines

-    the feature) in a LV2_Feature struct (as defined in lv2.h) to the UI's 

-    instantiate() function.

-    

-    These features may be used to specify how to pass data between the UI

-    and the plugin port buffers - see LV2UI_Write_Function for details.

-    

-    There are four features defined in this extension that hosts may want to

-    implement:

-

-<pre>

-    uiext:makeResident

-</pre>

-    If this feature is required by a UI the host MUST NEVER unload the shared

-    library containing the UI implementation during the lifetime of the host

-    process (e.g. never calling dlclose() on Linux). This feature may be 

-    needed by e.g. a Gtk UI that registers its own Glib types using 

-    g_type_register_static() - if it gets unloaded and then loaded again the 

-    type registration will break, since there is no way to unregister the 

-    types when the library is unloaded. The data pointer in the LV2_Feature

-    for this feature should always be set to NULL.

-

-<pre>

-    uiext:makeSONameResident

-</pre>

-    This feature is ELF specific - it should only be used by UIs that

-    use the ELF file format for the UI shared object files (e.g. on Linux).

-    If it is required by an UI the UI should also list a number of SO names

-    (shared object names) for libraries that the UI shared object

-    depends on and that may not be unloaded during the lifetime of the host

-    process, using the predicate @c uiext:residentSONames, like this:

-<pre>

-    <http://my.pluginui> uiext:residentSONames "libgtkmm-2.4.so.1", "libfoo.so.0"

-</pre>

-    The host MUST then make sure that the shared libraries with the given ELF

-    SO names are not unloaded when the plugin UI is, but stay loaded during

-    the entire lifetime of the host process. On Linux this can be accomplished

-    by calling dlopen() on the shared library file with that SO name and never

-    calling a matching dlclose(). However, if a plugin UI requires the 

-    @c uiext:makeSONameResident feature, it MUST ALWAYS be safe for the host to

-    just never unload the shared object containing the UI implementation, i.e.

-    act as if the UI required the @c uiext:makeResident feature instead. Thus

-    the host only needs to find the shared library files corresponding to the

-    given SO names if it wants to save RAM by unloading the UI shared object 

-    file when it is no longer needed. The data pointer for the LV2_Feature for

-    this feature should always be set to NULL.

-

-<pre>

-    uiext:noUserResize

-</pre>

-    If an UI requires this feature it indicates that it does not make sense

-    to let the user resize the main widget, and the host should prevent that.

-    This feature may not make sense for all UI types. The data pointer for the

-    LV2_Feature for this feature should always be set to NULL.

-

-<pre>

-    uiext:fixedSize

-</pre>

-    If an UI requires this feature it indicates the same thing as 

-    uiext:noUserResize, and additionally it means that the UI will not resize

-    the main widget on its own - it will always remain the same size (e.g. a

-    pixmap based GUI). This feature may not make sense for all UI types.

-    The data pointer for the LV2_Feature for this feature should always be set

-    to NULL.

-    

-    

-    UIs written to this specification do not need to be threadsafe - the 

-    functions defined below may only be called in the same thread as the UI

-    main loop is running in.

-    

-    Note that this UI extension is NOT a lv2:Feature. There is no way for a 

-    plugin to know whether the host that loads it supports UIs or not, and 

-    the plugin must ALWAYS work without the UI (although it may be rather 

-    useless unless it has been configured using the UI in a previous session).

-    

-    A UI does not have to be a graphical widget, it could just as well be a

-    server listening for OSC input or an interface to some sort of hardware

-    device, depending on the RDF class of the UI.

-    

-    The @c format parameter should either be 0 or a numeric ID for a "Transfer

-    mechanism". Transfer mechanisms are Features and may be defined in 

-    meta-extensions. They specify how to translate the data buffers passed

-    to this function to input data for the plugin ports. If a UI wishes to 

-    write data to an input port, it must list a transfer mechanism Feature 

-    for that port's class as an optional or required feature (depending on 

-    whether the UI will work without being able to write to that port or not).

-    The only exception is when the UI wants to write single float values to 

-    input ports of the class lv2:ControlPort, in which case @c buffer_size 

-    should always be 4, the buffer should always contain a single IEEE-754

-    float, and @c format should be 0.

-    

-    The numeric IDs for the transfer mechanisms are provided by a

-    feature <http://lv2plug.in/ns/ext/uri-map> with the map URI 

-    "http://lv2plug.in/ns/extensions/ui". Thus a UI that requires transfer

-    mechanism features also requires the URI Map feature, but this is 

-    implicit - the UI does not have to list the URI map feature as a required

-    or optional feature in it's RDF data.

-    

-    An UI MUST NOT pass a @c format parameter value (except 0) that has not

-    been returned by the host-provided URI mapping function for a 

-    host-supported transfer mechanism feature URI.

-

-    The UI MUST NOT try to write to a port for which there is no specified

-      class lv2:ControlPort, for which this function should be called

-      when the port value changes (it does not have to be called for every 

-      single change if the host's UI thread has problems keeping up with

-      

-      By default, the host should only call this function for input ports of

-      uiext:noPortNotification

-      uiext:plugin

-      uiext:portIndex

-      </pre>

-      For example, if you want the UI with uri 

-      <code><http://my.pluginui></code> for the plugin with URI 

-      <code><http://my.plugin></code> to get notified when the value of the 

-      output control port with index 4 changes, you would use the following 

-      in the RDF for your UI:

-      <pre>

-      <http://my.pluginui> uiext:portNotification [ uiext:plugin <http://my.plugin> ;

-                                                      uiext:portIndex 4 ] .

-      </pre>

-      and similarly with <code>uiext:noPortNotification</code> if you wanted

-      to prevent notifications for a port for which it would be on by default 

-      otherwise. The UI is not allowed to request notifications for ports of 

-      types for which no transfer mechanism is specified, if it does it should 

-      be considered broken and the host should not load it.

-      

-      The @c buffer is only valid during the time of this function call, so if 

-      the UI wants to keep it for later use it has to copy the contents to an

-      internal buffer.

-/** @file
- * C header for the LV2 URI Map extension <http://lv2plug.in/ns/ext/uri-map>.
- *
- * This extension defines a simple mechanism for plugins to map URIs to
- * integers, usually for performance reasons (e.g. processing events
- * typed by URIs in real time).  The expected use case is for plugins to
- * map URIs to integers for things they 'understand' at instantiation time,
- * and store those values for use in the audio thread without doing any string
- * comparison.  This allows the extensibility of RDF with the performance of
- * integers (or centrally defined enumerations).
