SYNOPSIS

10       #include <curl/curl.h>

13       curl_off_t *timep);

DESCRIPTION

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