- **Package:** libtmux_erlang
- **Language:** Erlang
- **Kind:** function
- **Source:** https://github.com/libtmux/libtmux-erlang/blob/d1b6308440cf9eb8f6647e7ae434bce60e849368/apps/libtmux_erlang/src/tmux_window_link.erl#L50

```
get(Server, SessionId, Index)
-spec get(tmux_server:t(),
          tmux_model:session_id(),
          index()) ->
             {ok, tmux_model:window_link()} |
             {error, map()}.
```

Read a current membership at the explicit session ID and index. The returned native row carries its registered owner and a new observation identity. Returns target_gone if the session or index is absent. This read does not make later actions atomic and does not refresh previously captured links.

Invalid indexes are rejected before I/O:

## Examples

```erlang
1> tmux_window_link:get(invalid_server, <<"$0">>, -1).
{error,#{code => invalid_option,path => [index]}}
```

## Parameters

- `Server` (`tmux_server:t()`)
- `SessionId` (`tmux_model:session_id()`)
- `Index` (`index()`)
