I've been trying to figure this out. What I'm doing right now, based on
reading src/main.c and lib/ftp.c in the curl distribution, is this:
curl_easy_setopt(easyhandle, CURLOPT_URL, "ftp://host/file");
curl_easy_setopt(easyhandle, CURLOPT_USERPWD, "1:2");
curl_easy_setopt(easyhandle, CURLOPT_NOBODY, TRUE);
curl_easy_setopt(easyhandle, CURLOPT_HEADER, TRUE);
curl_easy_setopt(easyhandle, CURLOPT_FILETIME, TRUE);
curl_easy_setopt(easyhandle, CURLOPT_FTPPORT, "-");
curl_easy_setopt(easyhandle, CURLOPT_VERBOSE, TRUE);
r = curl_easy_perform(easyhandle);
curl_easy_getinfo(easyhandle, CURLINFO_CONTENT_LENGTH_DOWNLOAD, &len);
printf("remote file size: %g\n", len);
I can see the result of the SIZE command in the debug output, and I can
see the Content-length: header in the header output, however, len is
always set to 0. Could it be that I'm asking curl_easy_getinfo() for
the wrong thing? None of the other options looks right. I suppose I can
parse the headers manually, if I have to.
Thanks, Philip Bock
