Progress function: dltotal always 0 ?

I'm using a progress function as set by CURLOPT_PROGRESSFUNCTION.
Whenever it's called dltotal is 0, and dlnow is set to the current
number of downloaded bytes.

Is this correct behaviour ? The docs seem to be silent as to
what should be passed in these args, unless I'm missing something.
