13# NAME
14
15CURLINFO_APPCONNECT_TIME - get the time until the SSL/SSH handshake is completed
16
17# SYNOPSIS
18
19~~~c
20#include <curl/curl.h>
21
22CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME,
23                           double *timep);
24~~~
25
26# DESCRIPTION
27
28Pass a pointer to a double to receive the time, in seconds, it took from the
29start until the SSL/SSH connect/handshake to the remote host was completed.
30This time is most often close to the CURLINFO_PRETRANSFER_TIME(3) time,
31except for cases such as HTTP pipelining where the pretransfer time can be
32delayed due to waits in line for the pipeline and more.
33
34When a redirect is followed, the time from each request is added together.
35
36See also the TIMES overview in the curl_easy_getinfo(3) man page.
