# 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.
|
|
|

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",
