Hello!
I have to make a c function for determining if some point its inside a set of elliptical geometries (I'm talking about a shared library, used like a function in the queries ). The geometries are defined in a table, so the function should iterate over a set of them. One option could be pass as a param to the funcition an array of HeapTupleHeader (if its posible), and other could be make a query inside the function for obtaining the geometries.
I can't find the way of doing none of them, someone knows if it's posible? And, of course, information and links are needed too.
Thank in advance.
