NAME

       CURLINFO_STARTTRANSFER_TIME_T - get the time until the first byte is received

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_STARTTRANSFER_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   first   byte    is    received    by    libcurl.    This    includes
       CURLINFO_PRETRANSFER_TIME_T(3) and also the time the server needs to calculate the result.

       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.

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