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.
