.TH CURLOPT_RESUME_FROM 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_RESUME_FROM \- set a point to resume transfer from
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from);
|
|
.SH 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
|
|
\fICURLOPT_RESUME_FROM_LARGE(3)\fP instead.
