```
val remove_hook :
  ?index:int ->
  t -> Libtmux.Options.scope -> string -> (unit, Libtmux.Error.t) result
```

Remove the local hook or one indexed array entry. An inherited hook may become effective again; this does not stop work it already started.

## Parameters

- `index?` (`int`)
- `arg1` (`t`)
- `arg2` (`Libtmux.Options.scope`)
- `arg3` (`string`)

## tmux command

The tmux commands behind `remove_hook`.

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

## tmux C API

The C declarations in tmux that implement these commands.

- [`cmd_set_hook_entry`](/en/tmux/latest/reference/c-variable-cmd_set_hook_entry/) (attribute)
- [`cmd_set_option_exec`](/en/tmux/latest/reference/c-function-cmd-set-option-c-cmd_set_option_exec/) (function)

## tmux hooks

Events that run tmux commands, with the scope each hook belongs to and where tmux fires it.
