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 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.

       This option is deprecated! Do not use it. Use  CURLOPT_MIMEPOST(3)  instead  after  having
       prepared mime data.

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);
