struct HttpPost *formpost = NULL, *lastptr = NULL;

curl_formadd(&formpost, &lastptr,
// CURLFORM_COPYNAME, "variable",
             CURLFORM_COPYCONTENTS, "some string",
curl_easy_setopt(curl, CURLOPT_ERRORBUFFER, &errorbuf);
curl_easy_setopt(curl, CURLOPT_FILE, &retval);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteMemoryCallback);
curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
curl_easy_setopt(curl, CURLOPT_URL, "http://some.url/");
int res = curl_easy_perform(curl);

this ends up in a GET request, however, if I remove the comment on
COPYNAME, curl makes a POST request.
