val wait_for_bytes :
  ?cancel:Cancellation.t ->
  ?timeout:float ->
  t ->
  text:string -> (Libtmux.Output.cursor, Libtmux.Output.wait_error) result
```

Consume future bytes until the nonempty pattern matches, including across Data boundaries. Maximum pattern: 64 KiB. Return the cursor at the match's end within its consumed event. Gaps stop matching; no rendered or earlier output is searched. Timeout leaves the subscription active.

## Parameters

- `cancel?` (`Cancellation.t`)
- `timeout?` (`float`)
- `arg1` (`t`)
- `text` (`string`)
