CURLOPT_HTTPPOST(3)	   Library Functions Manual	   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	 argu-
       ment.   Pass a pointer to a linked list of curl_httppost	structs	as pa-
       rameter.	 The easiest way to create such	a list,	is  to	use  curl_for-
       madd(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  CUR-
       LOPT_NOBODY(3) to 0.

DEFAULT
       NULL

PROTOCOLS
       This functionality affects http only

EXAMPLE
       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();
	 if(curl) {
	   curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
	   curl_easy_perform(curl);
	   curl_easy_cleanup(curl);
	 }
	 curl_formfree(formpost);
       }

DEPRECATED
       Deprecated in 7.56.0.

AVAILABILITY
       Added in	curl 7.1

RETURN VALUE
