This is a placeholder. It is very likely that the information below is false, so don't rely on it.
This hook can pass multiple parameters. In order to get additional parameters (up to 2 for this hook) passed to your function, you will have to hook in like this: add_filter('comment_edit_redirect', 'your_function', 10, 2); where 10 is your function's priority, and 2 is the number of parameters you want your function to accept. Note that your function should only return the first parameter.
This hook was introduced in WordPress 2.0.5, and will not work in earlier versions.
