- **Kind:** function
- **Source:** https://github.com/libtmux/libtmux-elixir/blob/66b9b1c3f3f3186428abdfda2c76f5cf87446710/lib/libtmux/control.ex#L367

```
request_close(control)
@spec request_close(t()) ::
        :ok | {:error, LibTmux.Error.t()}
```

Requests whole-epoch closure without claiming an operation or metadata slot.

Repeated requests for the same closing or proven-retired generation return
`:ok`. Success is a request or previously known retirement, not a cleanup
acknowledgement. A replacement Manager or epoch is never followed.

See the [worked example](api-examples.html#supervised-control).

## Parameters

- `control` (`t()`)
