CURLOPT_RESUME_FROM_LARGE(3) curl_easy_setopt options CURLOPT_RESUME_FROM_LARGE(3) NAME
CURLOPT_RESUME_FROM_LARGE - set a point to resume transfer from SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM_LARGE, curl_off_t from); 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. DEFAULT
