Function lilv_sys::lilv_plugin_get_value

pub unsafe extern "C" fn lilv_plugin_get_value(
    plugin: *const LilvPlugin, 
    predicate: *const LilvNode
) -> *mut LilvNodes

Get a value associated with the plugin in a plugin's data files. predicate must be either a URI or a QName.

Returns the ?object of all triples found of the form:

<plugin-uri> predicate ?object

May return NULL if the property was not found, or if object(s) is not sensibly represented as a LilvNodes (e.g. blank nodes). Return value must be freed by caller with lilv_nodes_free().
