NAME
CURLOPT_RESUME_FROM_LARGE - offset 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
0, not used
PROTOCOLS
HTTP, FTP, SFTP, FILE
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_off_t resume_position = GET_IT_SOMEHOW;
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);
/* ask for upload */
curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
/* set total data amount to expect */
curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, file_size);
/* Perform the request */
curl_easy_perform(curl);
}
AVAILABILITY
Added in 7.11.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
