```
val close : t -> (unit, Libtmux.Error.t) result
```

End an active subscription with Cancelled and discard pending data. Preserve an already ended subscription's terminal reason. Release and reap an unused lane; later calls retain cleanup failures. Does not stop the daemon. [`poll`](/en/ocaml/latest/reference/libtmux_unix-subscription-poll/) can still read the terminal event.

## Parameters

- `arg1` (`t`)
