NAME

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURL *curl_easy_duphandle(CURL *handle);

DESCRIPTION

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

RETURN VALUE

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