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_getinfo(curl, CURLINFO_APPCONNECT_TIME, &connect);


    if(CURLE_OK == res) {

    }
