ARC conversion help - CFErrorRef* and NSError**

ARC conversion is something we're having some issues with, but I won't bore you with the details. I'm trying to convert parts of our project to ARC and so of course there is a learning curve. Primarily between CF code and Cocoa. This one I'm stumped on as I'm just starting the CF/Cocoa _bridging part of my conversion.

+ (BOOL) addGroup: (ABGroup *) aGroup withError: (NSError **) error
{
     CFErrorRef* cfError = error;

     ABAddressBookRef addressBook = CFAutorelease(WebISSafe_ABAddressBookCreateWithOptions(NULL,NULL));
     if (!ABAddressBookAddRecord(addressBook, aGroup.record, cfError)) return NO;
     return ABAddressBookSave(addressBook, cfError);
}

I'm confused on how to properly bridge the CFErrorRef* and NSError**. I've tried a variety of things, but all give an error. I learn more by example than by definition so the reference docs don't always clarify things for me.

I appreciate it in advance.
