CURLINFO_NAMELOOKUP_TIME explained

CURLINFO_NAMELOOKUP_TIME - get the name lookup time

#include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NAMELOOKUP_TIME, double *timep);

Pass a pointer to a double to receive the total time in seconds 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 man page.

This functionality affects all supported protocols

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); } }

Added in curl 7.4.1

curl_easy_getinfo returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors.
