NAME

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

SYNOPSIS

10       #include <curl/curl.h>
11
12       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME_T,
13                                  curl_off_t *timep);
14

DESCRIPTION

16       Pass a pointer to a curl_off_t to receive the time, in microseconds, it
17       took  from  the start until the SSL/SSH connect/handshake to the remote
18       host was completed. This time is most often close to the  CURLINFO_PRE‐
19       TRANSFER_TIME_T(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 to‐
24       gether.

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

36         res = curl_easy_perform(curl);
37         if(CURLE_OK == res) {
38           res = curl_easy_getinfo(curl, CURLINFO_APPCONNECT_TIME_T, &connect);
39           if(CURLE_OK == res) {
40             printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", connect / 1000000,
41                    (long)(connect % 1000000));
42           }
43         }
44         /* always cleanup */
