CURLOPT_COOKIEJAR explained

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 *, zero terminated. This will make libcurl write all internally known cookies to the specified file when curl_easy_cleanup 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 CURLOPT_COOKIEFILE.

If the cookie jar file can't be created or written to (when the curl_easy_cleanup is called), libcurl will not and cannot report an error for this. Using CURLOPT_VERBOSE or CURLOPT_DEBUGFUNCTION 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.
