Re: What are double asterisks for?

It is a pointer to a pointer to an NSDictionary.

eg

NSDictionary *myDict = [NSDictionary dictionaryWithObjectsAndKeys:some, attributes, nil];
id rtf = [NSSomeObject initWithRTFDFileWrapper:someWrapper documentAttributes:&myDict];

For example:

- (id)initWithRTFDFileWrapper:(NSFileWrapper *)wrapper
documentAttributes:(NSDictionary **)docAttributes

Notice ** after the NSDictionary. I tried using this method and
passing a dictionary as an argument and I got a compile error:
Invoice.m:140: warning: passing arg 2 of
`initWithRTF:documentAttributes:' from incompatible pointer type

Can someone help please? Thanks.
