'fd' is serving double duty of also reporting the erorrs here and it's not really obvious from this hunk. The code above sets 'fd' to a variety of values e.g. -3 on some errors. This is really tricky and hard to follow. In this case we want a 'ret' variable which is set to the proper value and returned on error and fd returned on success or alternatively assigned to 'ret' right before returning it. This should make it possible to do it even without adding new not really useful labels.
