SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode  curl_easy_setopt(CURL *handle, CURLOPT_COOKIEJAR, char *file‐
12       name);

DESCRIPTION

15       Pass a filename as char *,  null-terminated.  This  will  make  libcurl
16       write   all  internally  known  cookies  to  the  specified  file  when
17       curl_easy_cleanup(3) is called. If no cookies are known, no  file  will
18       be created. Specify "-" as filename to instead have the cookies written
19       to stdout. Using this option also enables cookies for this session,  so
20       if  you for example follow a location it will make matching cookies get
21       sent accordingly.
22
23       Note that libcurl doesn't read any cookies from the cookie jar. If  you
24       want to read cookies from a file, use CURLOPT_COOKIEFILE(3).
25
26       If  the  cookie  jar  file  can't  be  created  or written to (when the
27       curl_easy_cleanup(3) is called), libcurl will not and cannot report  an
28       error  for  this.  Using CURLOPT_VERBOSE(3) or CURLOPT_DEBUGFUNCTION(3)
29       will get a warning to display, but that is the  only  visible  feedback
30       you get about this possibly lethal situation.
31
32       Since  7.43.0 cookies that were imported in the Set-Cookie format with‐
33       out a domain name are not exported by this option.
34
35       The application does not have to keep the string around  after  setting
36       this option.
