That error code is returned because you passed a bad parameter/argument to
the function. It has nothing to do with the download being successful or not.

You pass a long pointer to the function that doesn't point to a valid long.
By accident (or luck), it turned out to be NULL and libcurl found out and
returned an error. It could just as well have destroyed some random memory as
you didn't initialize the pointer properly.
