SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRETRANSFER_TIME, double *timep);

DESCRIPTION

       Pass  a  pointer  to  a  double  to  receive  the time, in seconds, it took from the start until the file
       transfer is just about to begin. This includes  all  pre-transfer  commands  and  negotiations  that  are
       specific  to  the  particular  protocol(s)  involved.  It  does  not involve the sending of the protocol-
       specific request that triggers a transfer.

       See also the TIMES overview in the curl_easy_getinfo(3) man page.

         res = curl_easy_perform(curl);
         if(CURLE_OK == res) {
           res = curl_easy_getinfo(curl, CURLINFO_PRETRANSFER_TIME, &pretransfer);
