NAME
       CURLINFO_PRETRANSFER_TIME_T  -  get  the  time  until the file transfer
       start

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRETRANSFER_TIME_T,
                                  curl_off_t *timep);

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

       When a redirect is followed,  the  time  from  each  request  is  added
       together.

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

EXAMPLE
       curl = curl_easy_init();

         res = curl_easy_perform(curl);
         if(CURLE_OK == res) {
           res = curl_easy_getinfo(curl, CURLINFO_PRETRANSFER_TIME_T, &pretransfer);
           if(CURLE_OK == res) {
             printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", pretransfer / 1000000,
                    (long)(pretransfer % 1000000));
           }
         }
