CURLOPT_RESUME_FROM(3) curl_easy_setopt options CURLOPT_RESUME_FROM(3)NAME
CURLOPT_RESUME_FROM - set a point 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 will
then append 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) instead.
DEFAULT
0, not used
PROTOCOLS
HTTP, FTP, SFTP, FILE
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
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);
}

CURLOPT_UPLOAD(3) curl_easy_setopt options CURLOPT_UPLOAD(3)NAME
CURLOPT_UPLOAD - enable data upload
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UPLOAD, long upload);
DESCRIPTION
The long parameter upload set to 1 tells the library to prepare for and perform an upload. The CURLOPT_READDATA(3) and CURLOPT_INFILE-
SIZE(3) or CURLOPT_INFILESIZE_LARGE(3) options are also interesting for uploads. If the protocol is HTTP, uploading means using the PUT
request unless you tell libcurl otherwise.
Using PUT with HTTP 1.1 implies the use of a "Expect: 100-continue" header. You can disable this header with CURLOPT_HTTPHEADER(3) as
usual.
If you use PUT to a HTTP 1.1 server, you can upload data without knowing the size before starting the transfer if you use chunked encoding.
You enable this by adding a header like "Transfer-Encoding: chunked" with CURLOPT_HTTPHEADER(3). With HTTP 1.0 or without chunked transfer,
you must specify the size.
DEFAULT
0, default is download

EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
/* we want to use our own read function */
curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_callback);
/* enable uploading */
curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
/* specify target */
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/to/newfile");
/* now specify which pointer to pass to our callback */
curl_easy_setopt(curl, CURLOPT_READDATA, hd_src);
/* Set the size of the file to upload */
curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize);
/* Now run off and do what you've been told! */
curl_easy_perform(curl);
