15 This function will return a new curl handle, a duplicate, using all the
16 options previously set in the input curl handle. Both handles can sub‐
17 sequently be used independently and they must both be freed with
18 curl_easy_cleanup(3).
19
20 All strings that the input handle has been told to point to (as opposed
21 to copy) with previous calls to curl_easy_setopt(3) using char * in‐
22 puts, will be pointed to by the new handle as well. You must therefore
23 make sure to keep the data around until both handles have been cleaned
24 up.
25
26 The new handle will not inherit any state information, no connections,
27 no SSL sessions and no cookies. It also will not inherit any share ob‐
28 ject states or options (it will be made as if CURLOPT_SHARE(3) was set
29 to NULL).
30
31 In multi-threaded programs, this function must be called in a synchro‐
32 nous way, the input handle may not be in use when cloned.
33
35 If this function returns NULL, something went wrong and no valid handle
36 was returned.
