| .TH CURLOPT_RESUME_FROM_LARGE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
 | |
| .SH NAME
 | |
| CURLOPT_RESUME_FROM_LARGE \- set a point to resume transfer from
 | |
| .SH SYNOPSIS
 | |
| .nf
 | |
| #include <curl/curl.h>
 | |
| 
 | |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM_LARGE,
 | |
|                           curl_off_t from);
 | |
| .SH 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.
 | |
| .SH DEFAULT
 | |
| 0, not used

 | |
| HTTP, FTP, SFTP, FILE

 | |
|   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);
