CURLOPT_COOKIEJAR(3)       curl_easy_setopt options       CURLOPT_COOKIEJAR(3)

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
       _easy_cleanup&section=3">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 _COOKIEFILE&section=3">CURLOPT_COOKIEFILE(3).

       If the cookie jar file can't be created or written to (when the
       _easy_cleanup&section=3">curl_easy_cleanup(3) is called), libcurl will not and cannot report an
       error for this. Using _VERBOSE&section=3">CURLOPT_VERBOSE(3) or _DEBUGFUNCTION&section=3">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);
       }
