	 curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
	 curl_easy_setopt(curl, CURLOPT_APPEND, 1L);

	 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

PROTOCOLS

       Most

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);
       }

AVAILABILITY

RETURN VALUE

       Returns CURLE_OK
