pointers and functions

[Ying Yang]

Hi,

Consider this function:

Node2* insertNode (Node1* node){
...
}
What is this function returning exactly?

1. a pointer of type Node2 OR
2. the contents of what Node2 references.

I think 1.

insertNode returns a pointer to Node2

It doesn't actually return "a pointer of type Node2". It returns "a
pointer to an object of type Node2". (But of course, it could return nil as
well, which technically doesn't point to anything.)

Saying "a pointer of type Node2" tends to imply that Node2 is a pointer
type and a pointer of that type is being returned, whereas here you are
returning a pointer, and what it points to is an object whose type is Node2.
But maybe I'm just being picky. :-)
