CURLINFO_CONNECT_TIME_T(3) Library Functions Manual CURLINFO_CONNECT_TIME_T(3)

CURLINFO_CONNECT_TIME_T - get the time until connect

#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONNECT_TIME_T,
                           curl_off_t *timep);

Pass a pointer to a curl_off_t to receive the total time in microseconds from the start until the connection to the remote host (or proxy) was completed.

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.
