Codex:

Short-circuits updating metadata of a specific type.

The dynamic portion of the hook name, `$meta_type`, refers to the meta object type (blog, post, comment, term, user, or any other type with an associated meta table). Returning a non-null value will effectively short-circuit the function. Possible hook names include: - `update_blog_metadata` - `update_post_metadata` - `update_comment_metadata` - `update_term_metadata` - `update_user_metadata`
