CURLINFO_APPCONNECT_TIME_T(3) Library Functions Manual CURLINFO_APPCONNECT_TIME_T(3)

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.

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));
}
}

curl_easy_cleanup(curl);
} }
