I'm inclined to agree, but off the top of my head an API user may wish to do: xdg_config_home(function_which_returns_NULL_on_error()) And wish for the error to propagate, but that may be considered sloppy programming and so it's better to treat a NULL input as a bug. Will fix this by calling assert(). Thanks.
