CURLINFO_APPCONNECT_TIME(3)                           Library Functions Manual

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_PRETRANSFER_TIME(3) time, except for cases such as HTTP
       pipelining where the pretransfer time can be delayed due to waits in
       line for the pipeline and more.

       When a redirect is followed, the time from each request is added
       together.

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

           double connect;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           res = curl_easy_perform(curl);
           if(CURLE_OK == res) {
             res = curl_easy_getinfo(curl, CURLINFO_APPCONNECT_TIME, &connect);
             if(CURLE_OK == res) {
               printf("Time: %.1f", connect);
             }
