> I avoid doing this. Just use `struct string { ... };'. It makes it clear what you're handling.

Well then imagine if Gtk made you write `struct GtkLabel`, etc. and you saw hundreds of `struct` on the screen taking up space in heavy UI code. Sometimes abstractions are worthwhile.

The main thing I dislike about typedefs is that you can't forward declare them.

If I know for sure I'm never going to need to do that then OK.

How do you mean? You can at least do things like

typedef struct foo foo;

and somewhere else

struct foo { … }

The usual solution for this is:

    typedef struct bla_s { ... } bla_t;
Now you have a struct named 'bla_s' and a type alias 'bla_t'. For the forward declaration you'd use 'bla_s'.

Using the same name also works just fine, since structs and type aliases live in different namespaces:

    typedef struct bla_t { ... } bla_t;
...also before that topic comes up again: the _t postfix is not reserved in the C standard :)

TBH, in that case the GtkLabel (and, indeed, the entire widget hierarchy) should be opaque pointers anyway.

If you're not using a struct as an abstraction, then don't typedef it. If you are, then hide the damn fields.
