Yes, we've never received any C++ examples to show. The moment we get one,
we'll make it available...

Yes you do that wrong.

The callback function must be a plain C function, not a C++ one. C++
functions all get an object pointer passed to them as an invisible (first)
argument, but C functions don't. So when libcurl calls the specified
function, there is no invisible argument, but your code falsely expects one.

Put your callback function within the extern "C" block, and things have a
much better chance to work!
