Wordpress Plugin, capture comment insertion

is there a hook to capture the moment a comment is inserted int开发者_开发百科o a post?

In wordpress docs, they say that 'edit_post' works because the comment count on that post is updated, but it doesn't work.

Thanks

There's an action hook called "wp_insert_comment" that's called from wp_insert_comment(). It passes the comment id and the new comment as an object. (wp-includes/comment.php on line 1245.)
