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 time-stamp includes all pre-transfer commands and negotiations that are  specific  to
       the  particular  protocol(s)  involved.  It  includes the sending of the protocol-specific
       instructions that trigger 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

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_off_t pretransfer;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           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\n",
                      pretransfer / 1000000,
                      (long)(pretransfer % 1000000));
             }
           }
           /* always cleanup */
           curl_easy_cleanup(curl);
         }
       }
