Erm, doing things on the C side isn't especially "elegant",
sorry. It's way more error-prone, more complicated to compile/link
against, and in your case it's not even portable (your version is
Unix-only).

Just write your select2 using an intermediate Hashtbl: it probably
won't be much slower (unless you have hundreds of fd maybe).
