Then you should really be using the curl-library mailing list.

Although, that list doesn't cover any binding in particular besides the
canonical C one. If there's a separate mailing list for the libcurl
FoxPro binding, you will probably get a better response there.

If this binding is anything like the C one, and from the snippet you've
posted it looks very close, there will be a CURLOPT_WRITEFUNCTION option
that sets up a callback function that receives writes. Make sure to return
a correct value from that function and this problem should go away.
