Re: C function to return tuple

Suppose I had the data that form the returning tuple in 5 variables like
this:
float8 xi = 1;
float8 yi = 2;
float8 xe = 3;
float8 ye = 4;
int32 id = 1;

In addition the function wouldn't have any input parameters. It just returns
a tuple of type d_type.
Can you tell me how it is possible to form the tuple? My problem here is
that I DON'T have HeapTupleHeaders i and e already formed (those two are of
p_type) so I have to form them somehow.
