What I was talking about then is the internal progress meter code (that
displays the numbers etc), not the ability to "hook" onto it. I have no plans
to remove any current interface call to libcurl.

That's how it works, yes.

That's unfortunately so. One plan would be to make libcurl open a separate
file descriptor (pipe) for cancellations, to include in the select() loop. A
curl_easy_abort_transfer() call should then be made to write to that file
descriptor and thus make the select() loop discover the request for abortion.

Still, that would require that you have a seperate thread with libcurl's
handle to use as input to that function. Further, that wouldn't work on
windows...

Thanks. With input such as yours, we'll make it even better!
