NAME
curl_easy_duphandle - Clone a libcurl session handle
SYNOPSIS
#include <curl/curl.h>
CURL *curl_easy_duphandle(CURL *handle);
DESCRIPTION
This function returns a new curl handle, a duplicate, using all the
options previously set in the input curl handle. Both handles can sub-
sequently be used independently and they must both be freed with
curl_easy_cleanup(3).
Any options that the input handle has been told to point to (as opposed
to copy) with previous calls to curl_easy_setopt(3), are 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 does not inherit any state information, no connections,
no SSL sessions and no cookies. It also does not inherit any share
object states or options (created as if CURLOPT_SHARE(3) was set to
NULL).
In multi-threaded programs, this function must be called in a synchro-
nous way, the input handle may not be in use when cloned.
EXAMPLE
CURL *curl = curl_easy_init();
CURL *nother;
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
nother = curl_easy_duphandle(curl);
res = curl_easy_perform(nother);
curl_easy_cleanup(nother);
curl_easy_cleanup(curl);
}

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