CURLINFO_APPCONNECT_TIME_T(3)                         Library Functions Manual

NAME
       CURLINFO_APPCONNECT_TIME_T - time until the SSL/SSH handshake completed

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME_T,
                                  curl_off_t *timep);

DESCRIPTION
       Pass a pointer to a curl_off_t to receive the time, in microseconds, 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_T(3) time, except for cases such as HTTP
       multiplexing where the pretransfer time can be delayed due to waits in
       line for the stream 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.

PROTOCOLS
       This functionality affects all supported protocols

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_off_t 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_T, &connect);
             if(CURLE_OK == res) {
               printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", connect / 1000000,
                      (long)(connect % 1000000));
             }
           }
           /* always cleanup */
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY
       Added in curl 7.61.0

RETURN VALUE

       CURLE_OK (0) means everything was OK, non-zero means an error occurred,
       see libcurl-errors(3).
