-/** @file
- * C header for the LV2 Dynamic Manifest extension
- * <http://lv2plug.in/ns/ext/dynmanifest>.
- * Revision: 1.1
- *
- * == Overview ==
- *
- * The LV2 API, on its own, cannot be used to write plugin libraries where
- * data is dynamically generated at runtime (e.g. API wrappers), since LV2
- * requires needed information to be provided in one or more static data (RDF)
- * files. This API addresses this limitation by extending the LV2 API.
- *
- * A host implementing support for this API should first detect that the plugin
- * library implements a dynamic manifest generator by examining its static
- * manifest file, then fetch data from the shared object file by accessing it as
- * usual (e.g., dlopen() and family) and using this API.
- *
- * The host is allowed to request regeneration of the dynamic manifest multiple
- * times, and the plugin library is expected to provide updated data if/when
- * possible. All data and references provided via this API before the last
- * regeneration of the dynamic manifest is to be considered invalid by the
- * host, including plugin descriptors whose URIs were discovered using this API.
- *
- * This API is extensible in a similar fashion as the LV2 API.
- *
- * == Accessing data ==
- *
- * Whenever a host wants to access data using this API, it could:
- *
- *  -# Call lv2_dyn_manifest_open();
- *  -# Create an empty resource identified by a FILE *;
- *  -# Get a "list" of exposed subject URIs using
- *     lv2_dyn_manifest_get_subjects();
- *  -# Call lv2_dyn_manifest_get_data() for each URI of interest, in order to
- *     get data related to that URI (either by calling the function subsequently
- *     with the same FILE * resource, or by creating more FILE * resources to
- *     perform parallel calls);
- *  -# Call lv2_dyn_manifest_close();
- *  -# Parse the content of the FILE * resource(s).
- *  -# Free/delete/unlink the FILE * resource(s).
- *
- * The content of the FILE * resources has to be interpreted by the host as a
- * regular file in Turtle syntax. This also means that each FILE * resource
- * should also contain needed prefix definitions, in case any are used.
- *
- * Each call to lv2_dyn_manifest_open() automatically implies the (re)generation
- * of the dynamic manifest on the library side.
- *
- * When such calls are made, data fetched from the involved library using this
- * API before such call is to be considered no more valid.
- *
- * In case the plugin library uses this same API to access other dynamic
- * manifests, it MUST implement some mechanism to avoid potentially endless
- * loops (such as A loads B, B loads A, etc.) and, in case such a loop is
- * detected, the operation MUST fail. For this purpose, use of a static boolean
- * flag is suggested.
- * 
- * == Threading rules ==
- *
- * All of the functions defined by this specification belong to the Discovery
- * class.
- *
- * Extensions to this specification which add new functions MUST declare in
- * which classes the functions belong, or define new classes for them.

-/** Dynamic manifest generator handle.
- *
- * This handle indicates a particular status of a dynamic manifest generator.
- * The host MUST NOT attempt to interpret it and, unlikely LV2_Handle, it is NOT
- * even valid to compare this to NULL. The dynamic manifest generator MAY use it
- * to reference internal data. */
