NAME
       curl_easy_duphandle - Clone a libcurl session handle

SYNOPSIS
       #include <curl/curl.h>

       CURL *curl_easy_duphandle(CURL *handle);


DESCRIPTION
       This  function  will  return  a new curl handle, a duplicate, using all the options previously set in the input
       curl handle.  Both  handles  can  subsequently  be  used  independently  and  they  must  both  be  freed  with
       curl_easy_cleanup(3).

       All  strings  that  the  input  handle  has  been  told to point to (as opposed to copy) with previous calls to
       curl_easy_setopt(3) using char * inputs, will be pointed to by the new handle as well. You must therefore  make
       sure to keep the data around until both handles have been cleaned up.

       The new handle will not inherit any state information, no connections, no SSL sessions and no cookies.

       Note  that even in multi-threaded programs, this function must be called in a synchronous way, the input handle
       may not be in use when cloned.

RETURN VALUE
       If this function returns NULL, something went wrong and no valid handle was returned.
