| 23 .SH NAME | |
| 24 curl_easy_duphandle - Clone a libcurl session handle | |
| 25 .SH SYNOPSIS | |
| 26 .B #include <curl/curl.h> | |
| 27 | |
| 28 .BI "CURL *curl_easy_duphandle(CURL *"handle ");" | |
| 29 | |
| 30 .SH DESCRIPTION | |
| 31 This function will return a new curl handle, a duplicate, using all the | |
| 32 options previously set in the input curl \fIhandle\fP. Both handles can | |
| 33 subsequently be used independently and they must both be freed with | |
| 34 \fIcurl_easy_cleanup(3)\fP. | |
| 35 | |
| 36 All strings that the input handle has been told to point to (as opposed to | |
| 37 copy) with previous calls to \fIcurl_easy_setopt(3)\fP using char * inputs, | |
| 38 will be pointed to by the new handle as well. You must therefore make sure to | |
| 39 keep the data around until both handles have been cleaned up. | |
| 40 | |
| 41 The new handle will \fBnot\fP inherit any state information, no connections, | |
| 42 no SSL sessions and no cookies. It also will not inherit any share object | |
| 43 states or options (it will be made as if \fICURLOPT_SHARE(3)\fP was set to | |
| 44 NULL). | |
| 45 | |
| 46 In multi-threaded programs, this function must be called in a synchronous way, | |
| 47 the input handle may not be in use when cloned. | |
| 48 .SH RETURN VALUE | |
| 49 If this function returns NULL, something went wrong and no valid handle was | |
| 50 returned. | |
