CURLOPT_POST(3) 					     curl_easy_setopt options						   CURLOPT_POST(3)

NAME

       CURLOPT_POST - request a HTTP POST

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POST, long post);

DESCRIPTION

       A  parameter set to 1 tells libcurl to do a regular HTTP post. This will also make the library use a "Content-Type: application/x-www-form-
       urlencoded" header. (This is by far the most commonly used POST method).

       Use one of CURLOPT_POSTFIELDS(3) or CURLOPT_COPYPOSTFIELDS(3) options to specify what data to post  and	CURLOPT_POSTFIELDSIZE(3)  or  CUR-
       LOPT_POSTFIELDSIZE_LARGE(3) to set the data size.

       Optionally,  you  can provide data to POST using the CURLOPT_READFUNCTION(3) and CURLOPT_READDATA(3) options but then you must make sure to
       not set CURLOPT_POSTFIELDS(3) to anything but NULL. When providing data with a callback, you must transmit it using chunked transfer-encod-
       ing  or	you  must  set the size of the data with the CURLOPT_POSTFIELDSIZE(3) or CURLOPT_POSTFIELDSIZE_LARGE(3) options. To enable chunked
       encoding, you simply pass in the appropriate Transfer-Encoding header, see the post-callback.c example.

       You can override the default POST Content-Type: header by setting your own with CURLOPT_HTTPHEADER(3).

       Using POST 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 POST to a HTTP 1.1 server, you can send data without knowing the size before starting the POST 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 in the request.

       When setting CURLOPT_POST(3) to 1, it will automatically set CURLOPT_NOBODY(3) to 0.

       If you issue a POST request and then want to make a HEAD or GET using the same re-used handle, you must explicitly set the new request type
       using CURLOPT_NOBODY(3) or CURLOPT_HTTPGET(3) or similar.

DEFAULT

       0, disabled

PROTOCOLS

       HTTP

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
