CURLINFO_N...KUP_TIME_T(3) Library Functions Manual CURLINFO_N...KUP_TIME_T(3) NAME CURLINFO_NAMELOOKUP_TIME_T - 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. PROTOCOLS This functionality affects all supported protocols EXAMPLE int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode result; curl_off_t namelookup; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); result = curl_easy_perform(curl); if(result == CURLE_OK) { result = curl_easy_getinfo(curl, CURLINFO_NAMELOOKUP_TIME_T, &namelookup); if(result == CURLE_OK) { printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", namelookup / 1000000, (long)(namelookup % 1000000)); } } /* always cleanup */ curl_easy_cleanup(curl); } } AVAILABILITY Added in curl 7.61.0 RETURN VALUE curl_easy_getinfo(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
