Yeah, You didn't understand. I've written about LARGE lists. You have 
iterator
to one element (e.g. it's 100001th element from begin) and you need to 
get previous iterator.

Why need I do it by myself when it can be default implementation?

It's wrong. Iterator is usefull structure (no matter about its internal) 
to store "pointer to the list/tree-item".
As you can understand every list/tree-item has (in valid realisation of 
course) all links to their neighbours.

It's wrong again. Because GTK+ team thinks that every programmer that 
uses GTK+
is stupid man(woman) who cannot write programs.
Sorry to all gtk+ developers but when I'was hacking through gtk+1.2.x's 
code I've always
think: "Why are these clever things hidden from me?".
