```
clear(Scope, Name0)
-spec clear(scope(), binary()) ->
               {ok, tmux_operation:completed()} |
               {error, tmux_operation:failure()}.
```

Leave an empty local hook array, masking inherited entries. This differs from `unset/2`, which restores inheritance. Global clear empties that defaults table. Performs I/O; existing effects already queued by tmux are not cancelled.

## Parameters

- `Scope` (`scope()`)
- `Name0` (`binary()`)

## tmux command

The tmux commands behind `clear/2`.

- [`set-hook`](/en/tmux/latest/manual/set-hook/)

## tmux C API

The C declarations in tmux that implement these commands.
