# NAME
CURLINFO_APPCONNECT_TIME_T - time until the SSL/SSH handshake completed
# SYNOPSIS
~~~c
#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
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.
# PROTOCOLS

# EXAMPLE
~~~c
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);
}
}
