+# NAME
+
+CURLOPT_COOKIEJAR - filename to store cookies to
+
+# SYNOPSIS
+
+~~~c
+#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.
+
+Using this option multiple times makes the last set string override the
+previous ones. Set it to NULL to disable its use again.
+
+# SECURITY CONCERNS
+
+libcurl cannot fully protect against attacks where an attacker has write
+access to the same directory where it is directed to save files. This is
+particularly sensitive if you save files using elevated privileges.
+
+# DEFAULT
+
+NULL
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+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%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
