# 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.
