CURLOPT_COOKIEJAR - file name to store cookies to
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEJAR, char *filename);
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.

HTTP
CURL *curl = curl_easy_init();

/* export cookies to this file when closing the handle */

Along with HTTP
Returns CURLE_OK if HTTP is supported, CURLE_UNKNOWN_OPTION if not, or
