POST(8) System Manager's Manual POST(8)NAME
POST - Handle a part of posting messages (used by sn news system)
SYNOPSIS
HELLO
DESCRIPTION
POST is the program that handles a part of posting messages to a newsserver.
It is executed by snntpd, after a POST command was sent by a newsreader. snntpd snntpd performs some checks, and runs POST to do some
additional checks. If the message is considered postable by POST, the actual posting is handled by snsend.
This program is used by the sn news system. You probably never have to use this program yourself.

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);
}

Returns CURLE_OK
