.TH CURLOPT_UPLOAD 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_UPLOAD \- enable data upload
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UPLOAD, long upload);
|
|
.SH DESCRIPTION
|
|
The long parameter \fIupload\fP set to 1 tells the library to prepare for and
|
|
perform an upload. The \fICURLOPT_READDATA(3)\fP and
|
|
\fICURLOPT_INFILESIZE(3)\fP or \fICURLOPT_INFILESIZE_LARGE(3)\fP 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 \fICURLOPT_HTTPHEADER(3)\fP 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
|
|
\fICURLOPT_HTTPHEADER(3)\fP. With HTTP 1.0 or without chunked transfer, you
|
|
must specify the size.
|
|

|
|
0, default is download
