I run the example ftpupload.c http://curl.haxx.se/lxr/source/docs/examples/ftpupload.c in CentOS release 4.6 (Final)
Kernel 2.6.9-67.EL on an i686,curl-devel-7.12.1-11.el4 but I get the failed result.The curl_easy_perform(curl) return 18.I find the error table that it means
  CURLE_PARTIAL_FILE (18) A file transfer was shorter or larger than expected. This happens when the server first reports an expected transfer size, and then delivers data that doesn't match the previously given size.
  But the file size equals the tranfer size.I don't know what's wrong.

  I see the target file "while-uploading.txt" but isn't renamed to "renamed-and-fine.txt".I guest that when the transfer file process fail,the proceedure terminate,so the following proceedure isn't excuted. I run many times and the result is the same.
  Thanks.
