NAME
CURLINFO_PRETRANSFER_TIME - get the time until the file transfer start
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRETRANSFER_TIME,
double *timep);
DESCRIPTION
Pass a pointer to a double to receive the time, in seconds, it took
from the start until the file transfer is just about to begin.
This time-stamp includes all pre-transfer commands and negotiations
that are specific to the particular protocol(s) involved. It includes
the sending of the protocol- specific protocol instructions that trig-

When a redirect is followed, the time from each request is added
together.
