```
LibTmux.Client.ResolveAttachmentAsync(cancellationToken: CancellationToken) -> Task<ClientAttachment?>
```

Reads where this client is looking now.

The three parts come from one reading of the client, so a client that
moves between sessions cannot yield a window from one and a pane from
another. A server that has stopped answering is not part of this: the
first read here is a live listing, and a live listing throws on
failure rather than answering null for it.

## Parameters

- `cancellationToken` (CancellationToken): Cancels the tmux commands.

## Returns

The session, window and pane the client is on, or null when the client
has detached or its session has since gone.
