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 *, null-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 does not 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 cannot 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, "https://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.
