focal (3) CURLINFO_APPCONNECT_TIME.3.gz

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  very  near  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.

         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);
           }
