+.TH CURLOPT_HTTPPOST 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_HTTPPOST \- specify the multipart formpost content
+.SH SYNOPSIS
+.nf
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST,
+                          struct curl_httppost *formpost);
+.SH 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 \fIformpost\fP 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 \fIcurl_formadd(3)\fP 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 \fICURLOPT_HTTPHEADER(3)\fP.
+
+When setting \fICURLOPT_HTTPPOST(3)\fP, it will automatically set
+\fICURLOPT_NOBODY(3)\fP to 0.
+
+This option is deprecated! Do not use it. Use \fICURLOPT_MIMEPOST(3)\fP
+instead after having prepared mime data.
+.SH DEFAULT
+NULL
+.SH PROTOCOLS
+HTTP
