Hi,

Well, the feature is to avoid transferring anything unless required. In the
case of my software, it needs to have a maximum limit to avoid downloading
files beyond that. I can also think of a wget like usecase for which
something like this might be useful.

Basically, it is about giving the flexibility to the caller to specify some
conditions under which libcurl will not download the resource. Since there
is no other way for the caller to find this out without downloading the
resource, it is a very useful feature.

Cheers,
Gautam

Why do you need this? You could easily count the downloaded size using
your
callback, and if it reaches your limit you can make your callback return
an
error back to the application. Isn't that good enough?

You could set your own custom return code in a struct (passed in from
the
application) or something so that you could even make it know that it
was
this particular condition occurred.
