I was thinking few time ago to add language support to do this from
vala using the offsetof() keyword. Will someone else find interesting
such a keyword in vala? Like in sizeof()
I was needing it to use kernel's list.h

Dear list,
I found this trick today, in case it is not already dinosaur..
[CCode (cname="G_STRUCT_OFFSET(MyBaseClassClass, my_function)")]
extern const int MyFunctionOffset;
basically you can call in this way any c macros that are otherwise not
directly bindable to vala, given that the return type of the macro is
known.
