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 microseconds from the start until the name
       resolving 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.

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_off_t 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_T, &namelookup);
             if(CURLE_OK == res) {
               printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", namelookup / 1000000,
                      (long)(namelookup % 1000000));
             }
           }
           /* always cleanup */
           curl_easy_cleanup(curl);
         }
       }
