Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# 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.

# EXAMPLE

int main(void)

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 */
