NAME

6       CURLINFO_APPCONNECT_TIME  - get the time until the SSL/SSH handshake is
7       completed
8

SYNOPSIS

10       #include <curl/curl.h>
11
12       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME, dou‐
13       ble *timep);
14

DESCRIPTION

16       Pass  a  pointer  to  a double to receive the time, in seconds, it took
17       from the start until the SSL/SSH connect/handshake to the  remote  host
18       was  completed.  This time is most often very near to the CURLINFO_PRE‐
19       TRANSFER_TIME(3) time, except for cases such as HTTP  pipelining  where
20       the  pretransfer time can be delayed due to waits in line for the pipe‐
21       line and more.
22
23       When a redirect is followed,  the  time  from  each  request  is  added
24       together.

26       See also the TIMES overview in the curl_easy_getinfo(3) man page.
