- * The URIHandler is an interface that is implemented by Source and Sink

+ * The #GstURIHandler is an interface that is implemented by Source and Sink
+ * #GstElement to unify handling of URI.
*
* An application can use the following functions to quickly get an element
* that handles the given URI for reading or writing
* (gst_element_make_from_uri()).
*
* Source and Sink plugins should implement this interface when possible.
