- **Kind:** function

```
libtmux.server._fetch_or_empty(server: Server, list_cmd: str, kwargs: t.Any) -> list[dict[str, t.Any]]
```

Wrap :func:`fetch_objs`: treat a not-yet-started server as empty.

A fresh :class:`~libtmux.Server` can be introspected via
:attr:`Server.sessions`, :attr:`Server.windows`, etc. before the
daemon is up. Other tmux errors, such as socket permission
failures, still propagate.
