NAME

       curl_formfree - free a previously build multipart/formdata HTTP POST chain

SYNOPSIS

       #include <curl/curl.h>

       void curl_formfree(struct curl_httppost *form);

DESCRIPTION

       curl_formfree()	is  used to clean up data previously built/appended with curl_formadd(3). This must be called when the data has been used,
       which typically means after curl_easy_perform(3) has been called.

       The pointer to free is the same pointer you passed to the CURLOPT_HTTPPOST option, which is the firstitem pointer from the  curl_formadd(3)
       invoke(s).

       form is the pointer as returned from a previous call to curl_formadd(3) and may be NULL.

RETURN VALUE

       None

NAME

       CURLOPT_HTTPPOST - specify the multipart formpost content

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST,
				 struct curl_httppost *formpost);

DESCRIPTION

       Tells  libcurl you want a multipart/formdata HTTP POST to be made and you instruct what data to pass on to the server in the formpost argu-
       ment.  Pass a pointer to a linked list of curl_httppost structs as parameter.  The easiest way to create such a list, is to  use  curl_for-
       madd(3) as documented. The data in this list must remain intact as long as the curl transfer is alive and is using it.

       Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header.  You can disable this header with CURLOPT_HTTPHEADER(3).

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

DEFAULT

       NULL

PROTOCOLS

       HTTP

EXAMPLE

       /* Fill in the file upload field. This makes libcurl load data from
	  the given file name when curl_easy_perform() is called. */
       curl_formadd(&formpost,
		    &lastptr,
		    CURLFORM_COPYNAME, "sendfile",
		    CURLFORM_FILE, "postit2.c",
		    CURLFORM_END);

       /* Fill in the filename field */
       curl_formadd(&formpost,
		    &lastptr,
		    CURLFORM_COPYNAME, "filename",
		    CURLFORM_COPYCONTENTS, "postit2.c",
		    CURLFORM_END);

       /* Fill in the submit field too, even if this is rarely needed */
       curl_formadd(&formpost,
		    &lastptr,
		    CURLFORM_COPYNAME, "submit",
		    CURLFORM_COPYCONTENTS, "send",
		    CURLFORM_END);

AVAILABILITY

       As long as HTTP is enabled

RETURN VALUE

       Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not.
