This time is most often close to the CURLINFO_PRETRANSFER_TIME_T(3) 33time, except for cases such as HTTP multiplexing where the pretransfer time 34can be delayed due to waits in line for the stream and more. 35 36When a redirect is followed, the time from each request is added together. 37 38See also the TIMES overview in the curl_easy_getinfo(3) man page. 39 40# EXAMPLE 41 42~~~c 43int main(void) 44{ 45 CURL *curl = curl_easy_init(); 46 if(curl) { 47 CURLcode res; 48 curl_off_t connect; 49 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); 50 res = curl_easy_perform(curl); 51 if(CURLE_OK == res) { 52 res = curl_easy_getinfo(curl, CURLINFO_APPCONNECT_TIME_T, &connect); 53 if(CURLE_OK == res) { 54 printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", connect / 1000000, 55 (long)(connect % 1000000)); 56 } 57 } 58 /* always cleanup */ 59 curl_easy_cleanup(curl); 60 } 61} 62~~~ 63 64# AVAILABILITY 65 66Added in 7.61.0 67 68# RETURN VALUE 69 70Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. 71
