Hi Robert,

In case you have the same problem I faced, ie you need to allocate
memory before bytes start to come in but you also can't
over-allocate...

I solved it this way: allocate at the point when the header is
received but before data arrives. This is pretty similar to what
Richard suggest, but not quite.

set CURLOPT_HEADERFUNCTION to a first function that will receive each
header line.
set CURLOPT_WRITEFUNCTION to a second function that saves the bytes in
the buffer.

At some point before actual data is received, the Header Function
receives a string starting with "Content-Length". The length to expect
follows the semi-colon.

Of course, if you're not interested in the contents at all and just
want to tell the user what size a download "would be", then I'd
investigate the first option Richard mentionned.
