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.

       Using this option multiple times makes the last set string override the previous ones. Set
       it to NULL to disable its use again.

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.
