     16 # NAME
     17 
     18 CURLINFO_APPCONNECT_TIME - get the time until the SSL/SSH handshake is completed
     19 
     20 # SYNOPSIS
     21 
     22 ~~~c
     23 #include <curl/curl.h>
     24 
     25 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME,
     26                            double *timep);
     27 ~~~
     28 
     29 # DESCRIPTION
     30 
     31 Pass a pointer to a double to receive the time, in seconds, it took from the
     32 start until the SSL/SSH connect/handshake to the remote host was completed.
     33 This time is most often close to the CURLINFO_PRETRANSFER_TIME(3) time, except
     34 for cases such as HTTP multiplexing where the pretransfer time can be delayed
     35 due to waits in line for the stream and more.
     36 
     37 When a redirect is followed, the time from each request is added together.
     38 
     39 See also the TIMES overview in the curl_easy_getinfo(3) man page.
