Hi Mikhail,

> BTW, WK2 C API has geneiric ref/unfer functions and GTK also does.
Would you please let us know more specific information on this, i.e. wiki
url or something that help our understanding?

Kind regards,

I've already mentioned the proposal at

but think (and since nobody replied so far) it deserves new topic and new
thread, so duplicating proposal again here.

As all the ref-counting EWK classes are inherited from WTF::RefCounted
it is possible now to have generic REF/UNREF functions in the public API
instead of 
having separate pair of such functions for every object.

To say in more details we could introduce 
struct Ewk_Ref_Counted Ewk_Ref_Counted;
and following generic functions:
EAPI Ewk_Ref_Counted*  ewk_ref(Ewk_Ref_Counted*);
EAPI  ewk_unref(Ewk_Ref_Counted*);

then Ewk_Back_Forward_List_Item  might be declared for instance as

typedef Ewk_Ref_Counted Ewk_Back_Forward_List_Item;

so that it's clear that Ewk_Back_Forward_List_Item is ref-countable 
(or we could just mention in docs that given object is ref counted).

Would like to hear your opinion about this proposal.

BTW, WK2 C API has geneiric ref/unfer functions and GTK also does.
