+# NAME
+
+CURLOPT_HTTPPOST - multipart formpost content
+
+# SYNOPSIS
+
+~~~c
+#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), libcurl automatically sets
+CURLOPT_NOBODY(3) to 0.
+
+# DEFAULT
+
+NULL

+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  struct curl_httppost *formpost;
+  struct curl_httppost *lastptr;
+
+  /* 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);
+
+  CURL *curl = curl_easy_init();

+    curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
