+.TH curl_easy_duphandle 3 "18 September 2001" "libcurl 7.9" "libcurl Manual"
+.SH NAME
+curl_easy_duphandle - Clone a libcurl session handle
+.SH SYNOPSIS
+.B #include <curl/curl.h>
+.sp
+.BI "CURL *curl_easy_duphandle(CURL *"handle ");"
+.ad
+.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()\fP.
+
+All strings that the input handle has been told to point to (as opposed to
+copy) with previous calls to \fIcurl_easy_setopt\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.
+
+This function was added in libcurl 7.9.
+.SH RETURN VALUE
+If this function returns NULL, something went wrong and no valid handle was
+returned.
