CURLOPT_POSTFIELDS(3)					     curl_easy_setopt options					     CURLOPT_POSTFIELDS(3)

NAME

       CURLOPT_POSTFIELDS - specify data to POST to server

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDS, char *postdata);

DESCRIPTION

       Pass  a	char * as parameter, pointing to the full data to send in a HTTP POST operation. You must make sure that the data is formatted the
       way you want the server to receive it. libcurl will not convert or encode it for you in any way. For example, the  web  server  may  assume
       that this data is url-encoded.

       The  data  pointed  to is NOT copied by the library: as a consequence, it must be preserved by the calling application until the associated
       transfer finishes.  This behaviour can be changed (so libcurl does copy the data) by setting the CURLOPT_COPYPOSTFIELDS(3) option.

       This POST is a normal application/x-www-form-urlencoded kind (and libcurl will set that Content-Type by default when this option is  used),
       which is commonly used by HTML forms. Change Content-Type with CURLOPT_HTTPHEADER(3).

       You  can  use  curl_easy_escape(3)  to  url-encode your data, if necessary. It returns a pointer to an encoded string that can be passed as
       postdata.

       Using CURLOPT_POSTFIELDS(3) implies CURLOPT_POST(3).

       If CURLOPT_POSTFIELDS(3) is explicitly set to NULL then libcurl will get the POST data from the read callback. If you want to send a  zero-
       byte POST set CURLOPT_POSTFIELDS(3) to an empty string, or set CURLOPT_POST(3) to 1 and CURLOPT_POSTFIELDSIZE(3) to 0.

       Using  POST  with  HTTP	1.1 implies the use of a "Expect: 100-continue" header.  You can disable this header with CURLOPT_HTTPHEADER(3) as
       usual.

       To make multipart/formdata posts (aka RFC2388-posts), check out the CURLOPT_HTTPPOST(3) option combined with curl_formadd(3).

DEFAULT

       NULL

PROTOCOLS

       HTTP

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
	 const char *data = "data to send";

	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 /* size of the POST data */
	 curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, 12L);

	 /* pass in a pointer to the data - libcurl will not copy */
	 curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);

	 curl_easy_perform(curl);
       }

AVAILABILITY

       Always

RETURN VALUE

       Returns CURLE_OK
