.TH CURLOPT_COOKIEJAR 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_COOKIEJAR \- file name to store cookies to
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIEJAR, char *filename);
.SH DESCRIPTION
Pass a \fIfilename\fP as char *, zero terminated. This will make libcurl write
all internally known cookies to the specified file when
\fIcurl_easy_cleanup(3)\fP 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 \fICURLOPT_COOKIEFILE(3)\fP.

If the cookie jar file can't be created or written to (when the
\fIcurl_easy_cleanup(3)\fP is called), libcurl will not and cannot report an
error for this. Using \fICURLOPT_VERBOSE(3)\fP or
\fICURLOPT_DEBUGFUNCTION(3)\fP 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.
