Yes, it's possible to pass a member function as a callback to
CURLOPT_WRITEFUNCTION. The fundamental trick is to pass a pointer
to a member function which is bound to a particular object, which
you can do with code like:

> std::bind1st(std::mem_fun(&FileTransferScheduler::progress_callback),
> this);

where ProgressCallback looks like:

I've posted more details about this in past so if you search
the list you should find all you need to know.
