function comment_access

7.x comment.module	`comment_access($op, $comment)`
6.x comment.module	`comment_access($op, $comment)`

This is *not* a hook_access() implementation. This function is called to determine whether the current user has access to a particular comment.

Authenticated users can edit their comments as long they have not been replied to. This prevents people from changing or revising their statements based on the replies to their posts.

Parameters

$op: The operation that is to be performed on the comment. Only 'edit' is recognized now.

$comment: The comment object.

Return value

TRUE if the current user has acces to the comment, FALSE otherwise.
