curl_easy_duphandle - Clone a libcurl session handle
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>#include</B> <B><curl/curl.h></B>
<B>CURL</B> <B>*curl_easy_duphandle(CURL</B> <B>*</B><I>handle</I><B>);</B>
</PRE>
<H2>DESCRIPTION</H2><PRE>
This function will return a new curl handle, a duplicate,
using all the options previously set in the input curl
<I>handle</I>. Both handles can subsequently be used indepen-
dently and they must both be freed with
<I>curl</I><B>_</B><I>easy</I><B>_</B><I>cleanup()</I>.
All strings that the input handle has been told to point
to (as opposed to copy) with previous calls to
<I>curl</I><B>_</B><I>easy</I><B>_</B><I>setopt</I> 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 <B>not</B> inherit any state information, no
connections, no SSL sessions and no cookies.
<B>Note</B> 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.
This function was added in libcurl 7.9.
</PRE>
<H2>RETURN VALUE</H2><PRE>
If this function returns NULL, something went wrong and no
valid handle was returned.
