I have looked and I have looked, it is not immediately clear to me how integer
arrays are passed to C function.
create table fubar (vars integer[]) ;
select c_function(vars) from fubar;
insert into fubar (vars) values ('{1,2,3,4,5,6}');
........
extern "C" c_function (varlena var)
{int * pn = (int *)VARDATA(var);
}
Now, what should "pn" have in it? I don't see my values until later on in the
array. I guess I am asking is what is the format of this type, and more
importantly, where is it documented. I looked in catalog and pg_types but it
wasn't clear it was defined there.
