CURLOPT_COOKIEFILE(3)					     curl_easy_setopt options					     CURLOPT_COOKIEFILE(3)

NAME

       CURLOPT_COOKIEFILE - file name to read cookies from

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEFILE, char *filename);

DESCRIPTION

       Pass  a	pointer  to  a zero terminated string as parameter. It should point to the file name of your file holding cookie data to read. The
       cookie data can be in either the old Netscape / Mozilla cookie data format or just regular HTTP headers	(Set-Cookie  style)  dumped  to  a
       file.

       It also enables the cookie engine, making libcurl parse and send cookies on subsequent requests with this handle.

       Given  an  empty  or non-existing file or by passing the empty string ("") to this option, you can enable the cookie engine without reading
       any initial cookies.

       This option only reads cookies. To make libcurl write cookies to file, see CURLOPT_COOKIEJAR(3).

       Exercise caution if you are using this option and multiple transfers may occur.	If you use the	Set-Cookie  format  and  don't	specify  a
       domain  then  the  cookie  is  sent  for any domain (even after redirects are followed) and cannot be modified by a server-set cookie. If a
       server sets a cookie of the same name then both will be sent on a future transfer to that server, likely not what you intended.	To address
       these issues set a domain in Set-Cookie (doing that will include sub-domains) or use the Netscape format.

       If you use this option multiple times, you just add more files to read.	Subsequent files will add more cookies.

       The application does not have to keep the string around after setting this option.

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
