Why? That's not an issue with libcurl. It doesn't care nor use the exc_fd_set
so setting those with fdset() will only trick the app.

I'm fine with allowing arguments to be NULL to then ignore those, and then you
can do exactly as you described previously that you're doing.

But I have no intention of making it even easier to extract the particular
sockets using that API since by using curl_multi_perform() and thus
curl_multi_fdset(), the application is more or less asking for _not_ knowing
about the particular sockets. The curl_multi_socket() is the right choice for
apps that do want to know.

I don't, but if you can explain to me why we need it I might change my mind.
