NAME
CURLINFO_PRETRANSFER_TIME_T - get the time until the file transfer
start
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRETRANSFER_TIME_T,
curl_off_t *timep);
DESCRIPTION
Pass a pointer to a curl_off_t to receive the time, in microseconds, it
took from the start until the file transfer is just about to begin.
This includes all pre-transfer commands and negotiations that are spe-
cific to the particular protocol(s) involved. It does not involve the
sending of the protocol- specific request that triggers a transfer.
When a redirect is followed, the time from each request is added to-
gether.
See also the TIMES overview in the curl_easy_getinfo(3) man page.

res = curl_easy_getinfo(curl, CURLINFO_PRETRANSFER_TIME_T, &pretransfer);
