> How does select() know the FD_SETSIZE?

It doesn't have to. The actual number of descriptors is passed in, and the API presumably assumes that FD_SETSIZE is bigger than that (or else the caller would have crashed writing to invalid memory).

I don't see why we'd make it a parameter though. If we have all the descriptors, just allocate a big enough array and pass it in?
