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.
