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  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

       HTTP

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

       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.
