val waitFor:
        cancellationToken: CancellationToken -> request: PaneWaitRequest -> pane: LibTmux.Pane -> Task<PaneWaitResult>
```

Waits as the request describes: patterns, stop patterns, or any output.

Running out of time returns the outcome <c>TimedOut</c>; only <c>Mirror.waitUntil</c> raises instead.

## Parameters

- `cancellationToken` (`CancellationToken`)
- `request` (`PaneWaitRequest`)
- `pane` (`LibTmux.Pane`)

## Raises

- [`LibTmux.TmuxPaneException`](/en/csharp/latest/reference/libtmux-tmuxpaneexception/): The pane's program had already exited.
- [`LibTmux.TmuxObjectNotFoundException`](/en/csharp/latest/reference/libtmux-tmuxobjectnotfoundexception/): tmux no longer has the pane.
