16# NAME
17
18CURLINFO_APPCONNECT_TIME - get the time until the SSL/SSH handshake is completed
19
20# SYNOPSIS
21
22~~~c
23#include <curl/curl.h>
24
25CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME,
26                           double *timep);
27~~~
28
29# DESCRIPTION
30
31Pass a pointer to a double to receive the time, in seconds, it took from the
32start until the SSL/SSH connect/handshake to the remote host was completed.
33This time is most often close to the CURLINFO_PRETRANSFER_TIME(3) time, except
34for cases such as HTTP multiplexing where the pretransfer time can be delayed
35due to waits in line for the stream and more.
36
37When a redirect is followed, the time from each request is added together.
38
39See also the TIMES overview in the curl_easy_getinfo(3) man page.
