Expand a little. - mention the type name of the return code - avoid stating which exact return codes that might be returned, as that varies over time, builds and conditions - avoid stating some always return OK - refer to the manpage documenting all the return codes Closes #15900

# 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 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.
