## 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 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);
    }
