+
+    <para><function>sd_bus_list_names()</function> retrieves information about the registered names on a bus.
+    If <parameter>acquired</parameter> is not <constant>NULL</constant>, this function calls
+    <ulink url="https://dbus.freedesktop.org/doc/dbus-specification.html#bus-messages-list-names">
+    org.freedesktop.DBus.ListNames</ulink> to retrieve the list of currently-owned names on the bus. If
+    <parameter>acquired</parameter> is not <constant>NULL</constant>, the function calls
+    <ulink url="https://dbus.freedesktop.org/doc/dbus-specification.html#bus-messages-list-activatable-names">
+    org.freedesktop.DBus.ListActivableNames</ulink> to retrieve the list of all names on the bus that can be
+    activated. Note that ownership of any string arrays returned by <function>sd_bus_list_names()</function>
+    is transferred to the caller and hence, the caller is responsible for freeing any results stored by
+    <function>sd_bus_list_names()</function> in <parameter>acquired</parameter> and
+    <parameter>activatable</parameter>.</para>
