CURLOPT_RESUME_FROM(3)

CURLOPT_RESUME_FROM(3curl_easy_setopt optionCURLOPT_RESUME_FROM(3)

NAME

     CURLOPT_RESUME_FROM - set a point to resume transfer from

SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM,
     long from);

DESCRIPTION

     Pass a long 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.

     If you need to resume a transfer beyond the 2GB  limit,  use
     CURLOPT_RESUME_FROM_LARGE(3) instead.

DEFAULT

     0, not used

PROTOCOLS

     HTTP, FTP, SFTP, FILE

EXAMPLE

     CURL *curl = curl_easy_init();
     if(curl) {
       curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com");

       /* resume upload at byte index 200 */
       curl_easy_setopt(curl, CURLOPT_RESUME_FROM, 200L);

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

       /* set total data amount to expect */
       curl_easy_setopt(curl, CURLOPT_INFILESIZE, size_of_file);

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