+/**
+ * e_source_registry_server_load_resource:
+ * @server: an #ESourceRegistryServer
+ * @resource: a #GResource containing data source key files
+ * @path: the path to the data source key files inside @resource
+ * @flags: permission flags for files loaded from @path
+ * @error: return location for a #GError, or %NULL
+ *
+ * Loads data source key files from @resource by enumerating the children
+ * at @path and calling e_source_registry_server_load_file() on each child.
+ * Because multiple errors can occur when loading multiple files, @error is
+ * only set if @path is invalid.  If a key file fails to load, the error is
+ * broadcast through the #ESourceRegistryServer::load-error signal.
+ *
+ * Returns: %TRUE if @path was successfully located, but this does not
+ *          imply the key files were successfully loaded
+ *
+ * Since: 3.8
