CURLINFO_APPCONNECT_TIME_T − get the time until the SSL/SSH handshake is completed
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME_T, curl_off_t *timep);
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 very near 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.
