# NAME
CURLINFO_APPCONNECT_TIME - get the time until the SSL/SSH handshake is completed
# SYNOPSIS
~~~c
#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 close 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.
# PROTOCOLS
All
# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
double 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, &connect);
if(CURLE_OK == res) {
printf("Time: %.1f", connect);
}
}
/* always cleanup */
curl_easy_cleanup(curl);
}
}
~~~
# AVAILABILITY
