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¶
