NAME
CURLINFO_NAMELOOKUP_TIME_T - get the name lookup time in microseconds
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NAMELOOKUP_TIME_T,
curl_off_t *timep);
DESCRIPTION
Pass a pointer to a curl_off_t to receive the total time in

res = curl_easy_perform(curl);
if(CURLE_OK == res) {
res = curl_easy_getinfo(curl, CURLINFO_NAMELOOKUP_TIME_T, &namelookup);
if(CURLE_OK == res) {
printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", namelookup / 1000000,
