loadBuffer(
  name: string,
  data: string | Uint8Array,
): Promise<void>
```

Fill a paste buffer from data fed through tmux's stdin.

Use this over [`Server.setBuffer`](/en/ts/latest/reference/server-server-setbuffer/) for anything large or binary: that
one passes its data as a command-line argument, and this one does not.

## Examples

```ts
await server.loadBuffer("payload", new Uint8Array([0x68, 0x69]));
```

## Parameters

- `name` (`string`)
- `data` (`string | Uint8Array`)

## tmux command

The tmux commands behind `loadBuffer`.

- [`load-buffer`](/en/tmux/latest/manual/load-buffer/)

## tmux C API

The C declarations in tmux that implement these commands.

- [`cmd_load_buffer_entry`](/en/tmux/latest/reference/c-variable-cmd_load_buffer_entry/) (attribute)
- [`cmd_load_buffer_exec`](/en/tmux/latest/reference/c-function-cmd-load-buffer-c-cmd_load_buffer_exec/) (function)
