#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 close to the CURLINFO_PRETRANSFER_TIME_T(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.

CURL *curl = curl_easy_init();

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
