CURLOPT_RESUME_FROM_LARGE(3)

CURLOPT_R...FROM_LARGE(3)  curl_easy_setopt options  CURLOPT_R...FROM_LARGE(3)

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  re‐
       sume).  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  lo‐
       cal/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);
       }
