# CURLOPT\_RESUME\_FROM(3)

offset to resume transfer from

## NAME

CURLOPT\_RESUME\_FROM - offset 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 then appends 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)](/CURLOPT_RESUME_FROM_LARGE/3.md)* instead.

## DEFAULT

0, not used

## PROTOCOLS

HTTP, FTP, SFTP, FILE

## EXAMPLE

```
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    long size_of_file;
    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);
  }
}
```
