NAME

       CURLOPT_COOKIEJAR - filename to store cookies to

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       Pass  a  filename  as a char *, null-terminated. This makes libcurl write all internally known cookies to
       the specified file when curl_easy_cleanup(3) is called. If no cookies are kept in memory at that time, no
       file is 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 redirect it makes matching  cookies
       get sent accordingly.

       Note  that  libcurl  does  not  read  any cookies from the cookie jar specified with this option. 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
       does  not  and  cannot  report  an  error  for this. Using CURLOPT_VERBOSE(3) or CURLOPT_DEBUGFUNCTION(3)
       displays a warning, but that is the only visible feedback you get about this possibly lethal situation.

       Cookies are 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

       This functionality affects http only

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           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");

           res = curl_easy_perform(curl);

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

AVAILABILITY

       Added in curl 7.9

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.
