NAME

CURLINFO_NAMELOOKUP_TIME - get the name lookup time

SYNOPSIS

#include <curl/curl.h>

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

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    double namelookup;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    res = curl_easy_perform(curl);
    if(CURLE_OK == res) {
      res = curl_easy_getinfo(curl, CURLINFO_NAMELOOKUP_TIME, &namelookup);
      if(CURLE_OK == res) {
        printf("Time: %.1f", namelookup);
      }
    }
    /* always cleanup */
    curl_easy_cleanup(curl);
  }
}
