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 :)

People getting hung up on `_t` usage being reserved for posix need to lighten up. I doubt they'll clash with my definitions and if does happen in the future, I'll change the typedef name.

Yes, using the same Gtk example, the way you’d forward declare GtkLabel without including gtklabel.h in your header would be:

    struct _GtkLabel;
    typedef struct _GtkLabel GtkLabel;
    // Use GtkLabel* in declarations
