val unlink_window_at :
  ?allow_kill:bool ->
  t -> Libtmux.Session.target -> index:int -> (unit, Libtmux.Error.t) result
```

Without `allow_kill`, tmux rejects removal of the last link to a window.

## Parameters

- `allow_kill?` (`bool`)
- `arg1` (`t`)
- `arg2` (`Libtmux.Session.target`)
- `index` (`int`)

## tmux command

The tmux commands behind `unlink_window_at`.

- [`unlink-window`](/en/tmux/latest/manual/unlink-window/)

## tmux C API
