CURLOPT_HTTPPOST(3)                 libcurl                CURLOPT_HTTPPOST(3)

NAME
       CURLOPT_HTTPPOST - multipart formpost content

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       This option is deprecated. Use CURLOPT_MIMEPOST(3) instead.

       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
       argument.  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_formadd(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

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