curl_easy_duphandle - Clone a libcurl session handle
CURL *curl_easy_duphandle(CURL *handle);
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().
All strings that the input handle has been told to point to (as opposed to copy) with pre-
vious calls to curl_easy_setopt 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
The new handle will not inherit any state information, no connections, no SSL sessions and
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.
This function was added in libcurl 7.9.
If this function returns NULL, something went wrong and no valid handle was returned.
Surely there are some, you tell me!
