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.
