|
.SH NAME
|
|
curl_easy_duphandle - Clone a libcurl session handle
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
|
|
.BI "CURL *curl_easy_duphandle(CURL *"handle ");"
|
|
|
|
.SH DESCRIPTION
|
|
This function will return a new curl handle, a duplicate, using all the
|
|
options previously set in the input curl \fIhandle\fP. Both handles can
|
|
subsequently be used independently and they must both be freed with
|
|
\fIcurl_easy_cleanup(3)\fP.
|
|
|
|
All strings that the input handle has been told to point to (as opposed to
|
|
copy) with previous calls to \fIcurl_easy_setopt(3)\fP 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 \fBnot\fP inherit any state information, no connections,
|
|
no SSL sessions and no cookies.
|
|
|
|
\fBNote\fP 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.
|
|
.SH RETURN VALUE
|
|
If this function returns NULL, something went wrong and no valid handle was
|
|
returned.
