although I've read some of the NSError documentation, there are still two things that are unclear to me :

1) Why are "double pointer" NSError** used instead of a single pointer ? 2) When debugging, how should I read the NSError objects ? With "po theError" or "po *theError" ?


 I wrote an article a while ago:

	http://www.zathras.de/howmemorymanagementworks.htm

it has lots of pictures explaining what memory is and how it works. Maybe that'll help you build a metaphor in your head that makes it obvious why NSError** is used.
