NAME

       CURLOPT_RESUME_FROM_LARGE - set a point 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);
       }
