NAME

       CURLOPT_RESUME_FROM_LARGE - offset to resume transfer from

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM_LARGE,
                                 curl_off_t from);

DESCRIPTION

       Pass  a  curl_off_t  as parameter. It contains the offset in number of bytes that you want
       the transfer to start from. Set this option to 0 to  make  the  transfer  start  from  the
       beginning  (effectively  disabling  resume).  For  FTP,  set this option to -1 to make the
       transfer start from the end of the target file (useful to continue an interrupted upload).

       When doing uploads with FTP, the resume position is where in the local/source file libcurl
       should try to resume the upload from and it will then append the source file to the remote
       target file.

DEFAULT

       0, not used

PROTOCOLS

       HTTP, FTP, SFTP, FILE

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_off_t resume_position = GET_IT_SOMEHOW;
         curl_off_t file_size = GET_IT_SOMEHOW_AS_WELL;

         curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com");

         /* resuming upload at this position, possibly beyond 2GB */
         curl_easy_setopt(curl, CURLOPT_RESUME_FROM_LARGE, resume_position);

         /* ask for upload */
         curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

         /* set total data amount to expect */
         curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, file_size);

         /* Perform the request */
         curl_easy_perform(curl);
       }
