37 *
38 * Request internal information from the curl session with this function. The

40 * pointer to a double (as the documentation describes elsewhere). The data
41 * pointed to will be filled in accordingly and can be relied upon only if the

43 * performed transfer, all results from this function are undefined until the

55 * passed in. Duplicating a handle could only be a matter of cloning data and
56 * options, internal state info and things like persistent connections cannot
57 * be transferred. It is useful in multithreaded applications when you can run
58 * curl_easy_duphandle() for each new thread to avoid a series of identical
59 * curl_easy_setopt() invokes in every thread.
