That is why I want to use the internal default function by setting the
option to NULL: what does NULL mean? chr(0)? int 0? I tried both with same
results.

I made

ferrh=fcreate("error.txt)

and I did
curl_easy_setopt(hcurl, CURLOPT_WRITEDATA, @ferrh)

with same results.

I will keep trying some other options.

That's a legitimate response to options that make no sense.
