NAME¶
curl_easy_duphandle - Clone a libcurl session handle
SYNOPSIS¶
#include <curl/curl.h>
CURL *curl_easy_duphandle(CURL *handle);
DESCRIPTION¶
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(3).
All strings that the input handle has been told to point to (as opposed to copy)
with previous calls to
curl_easy_setopt(3) 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
not inherit any state information, no connections, no
SSL sessions and no cookies.
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.
RETURN VALUE¶
If this function returns NULL, something went wrong and no valid handle was
returned.
