Description [src]

The type of the enumerate function in GDBusSubtreeVTable.

This function is called when generating introspection data and also when preparing to dispatch incoming messages in the event that the G_DBUS_SUBTREE_FLAGS_DISPATCH_TO_UNENUMERATED_NODES flag is not specified (ie: to verify that the object path is valid).

Hierarchies are not supported; the items that you return should not contain the / character.

The return value will be freed with g_strfreev().

Available since: 2.26
