- * DESCRIPTION
- *
- * Request internal information from the curl session with this function. The
- * third argument MUST be a pointer to a long, a pointer to a char * or a
- * pointer to a double (as the documentation describes elsewhere). The data
- * pointed to will be filled in accordingly and can be relied upon only if the

- * performed transfer, all results from this function are undefined until the
- * transfer is completed.

- * Creates a new curl session handle with the same options set for the handle
- * passed in. Duplicating a handle could only be a matter of cloning data and
- * options, internal state info and things like persistant connections cannot
- * be transfered. It is useful in multithreaded applications when you can run
- * curl_easy_duphandle() for each new thread to avoid a series of identical
- * curl_easy_setopt() invokes in every thread.

- *
- * It does keep: live connections, the Session ID cache, the DNS cache and the
