CURLINFO_NAMELOOKUP_TIME_T (original) (raw)

CURLINFO_NAMELOOKUP_TIME_T explained

CURLINFO_NAMELOOKUP_TIME_T - get the name lookup time in microseconds

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

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 man page.

This functionality affects all supported protocols

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); } }

Added in curl 7.61.0

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.
