NAME

       CURLINFO_STARTTRANSFER_TIME - get the time until the first byte is received

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       Pass  a  pointer to a double to receive the time, in seconds, it took from the start until the first byte
       is received by libcurl. This includes CURLINFO_PRETRANSFER_TIME(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.

           double start;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
           res = curl_easy_perform(curl);
           if(CURLE_OK == res) {
             res = curl_easy_getinfo(curl, CURLINFO_STARTTRANSFER_TIME, &start);
             if(CURLE_OK == res) {
               printf("Time: %.1f", start);
             }
           }
