SYNOPSIS

10       #include <curl/curl.h>
11
12       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_STARTTRANSFER_TIME,
13                                  double *timep);
14

DESCRIPTION

16       Pass a pointer to a double to receive the time,  in  seconds,  it  took
17       from  the  start  until the first byte is received by libcurl. This in‐
18       cludes CURLINFO_PRETRANSFER_TIME(3) and also the time the server  needs
19       to calculate the result.
20
21       When  a  redirect  is followed, the time from each request is added to‐
22       gether.
