- .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.
- .SH "SEE ALSO"
- .BR curl_easy_init "(3)," curl_easy_cleanup "(3)," curl_easy_reset "(3),"
- .BR curl_global_init "(3)"
