                     26: CURLOPT_RESUME_FROM \- set a point to resume transfer from
                     27: .SH SYNOPSIS
                     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.
