CURLINFO_APPCONNECT_TIME(3) Library Functions Manual CURLINFO_APPCONNECT_TIME(3)

NAME

CURLINFO_APPCONNECT_TIME - get the time until the SSL/SSH handshake is completed

SYNOPSIS


#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME,
double *timep);

DESCRIPTION

Pass a pointer to a double to receive the time, in seconds, 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(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.

PROTOCOLS

EXAMPLE


int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;

res = curl_easy_perform(curl);
if(CURLE_OK == res) {
res = curl_easy_getinfo(curl, CURLINFO_APPCONNECT_TIME, &connect);
if(CURLE_OK == res) {
printf("Time: %.1f", connect);
}
}
/* always cleanup */
curl_easy_cleanup(curl);
}
}
