```
LibTmux.Server.FromEnvironment(environment: IReadOnlyDictionary<string, string>?) -> Server
```

Returns the server whose pane this process was spawned in.

Only the socket path is used. The pid and session id in <c>TMUX</c> are
frozen at pane spawn, and the session id goes stale as soon as the
pane's window moves between sessions. Costs no tmux subprocess.

## Parameters

- `environment` (`IReadOnlyDictionary<string, string>?`): The environment, or null for the process.

## Returns

An unmaterialized handle for the exported socket.

## Raises

- [`TmuxObjectNotFoundException`](/en/csharp/latest/reference/libtmux-tmuxobjectnotfoundexception/): The environment does not name a tmux server.
