Edit Question
Title
Body
This concept seems to trouble me. Why does an NSError object need its pointer passed to a method that is modifying the object? For instance, wouldn't just passing a reference to the error do the same thing? NSError *anError; [myObjc doStuff:withAnotherObj error:error]; and then in doStuff: - (void)doStuff:(id)withAnotherObjc error:(NSError *)error { // something went bad! [error doSomethingToTheObject]; } Why doesn't the above work like most other object messaging patterns work? Why must instead we use error:(NSError **)error?
