        !            28: #include <curl/curl.h>
        !            29: 
        !            30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from);
        !            31: .SH DESCRIPTION
        !            32: Pass a long as parameter. It contains the offset in number of bytes that you
        !            33: want the transfer to start from. Set this option to 0 to make the transfer
        !            34: start from the beginning (effectively disabling resume). For FTP, set this
        !            35: option to -1 to make the transfer start from the end of the target file
        !            36: (useful to continue an interrupted upload).
        !            37: 
        !            38: When doing uploads with FTP, the resume position is where in the local/source
        !            39: file libcurl should try to resume the upload from and it will then append the
        !            40: source file to the remote target file.
        !            41: 
        !            42: If you need to resume a transfer beyond the 2GB limit, use
        !            43: \fICURLOPT_RESUME_FROM_LARGE(3)\fP instead.
