NAME

       CURLOPT_COOKIEJAR - file name to store cookies to

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       Pass  a  filename  as char *, zero terminated. This will make libcurl write all internally
       known cookies to the specified file when curl_easy_cleanup(3) is called. If no cookies are
       known,  no  file  will  be  created.  Specify  "-" as filename to instead have the cookies
       written to stdout. Using this option also enables cookies for this session, so if you  for
       example follow a location it will make matching cookies get sent accordingly.

       Note  that  libcurl  doesn't  read  any  cookies  from the cookie jar. If you want to read
       cookies from a file, use CURLOPT_COOKIEFILE(3).

       If the cookie jar file can't be created or written to (when  the  curl_easy_cleanup(3)  is
       called), libcurl will not and cannot report an error for this. Using CURLOPT_VERBOSE(3) or
       CURLOPT_DEBUGFUNCTION(3) will get a warning to display,  but  that  is  the  only  visible
       feedback you get about this possibly lethal situation.

       Since 7.43.0 cookies that were imported in the Set-Cookie format without a domain name are
       not exported by this option.

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

DEFAULT

       NULL

PROTOCOLS

       HTTP

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/foo.bin");

         /* export cookies to this file when closing the handle */
         curl_easy_setopt(curl, CURLOPT_COOKIEJAR, "/tmp/cookies.txt");

         ret = curl_easy_perform(curl);

         /* close the handle, write the cookies! */
         curl_easy_cleanup(curl);
       }

AVAILABILITY

       Along with HTTP

RETURN VALUE

       Returns CURLE_OK if HTTP is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY
       if there was insufficient heap space.
