CURLINFO_APPCONNECT_TIME(3) Library Functions ManualCURLINFO_APPCONNECT_TIME(3)
NAME
CURLINFO_APPCONNECT_TIME - get the time until the SSL/SSH handshake is
completed
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME,
double *timep);
DESCRIPTION
Pass a pointer to a double to receive the time, in seconds, it took from
the start until the SSL/SSH connect/handshake to the remote host was
completed. This time is most often close to the CURLINFO_PRETRANS-
FER_TIME(3) time, except for cases such as HTTP multiplexing where the
pretransfer time can be delayed due to waits in line for the stream and
more.
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_perform(curl);
if(CURLE_OK == res) {
res = curl_easy_getinfo(curl, CURLINFO_APPCONNECT_TIME, &connect);
if(CURLE_OK == res) {
