NAME
       CURLOPT_TIMEOUT_MS - maximum time the transfer is allowed to complete

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEOUT_MS, long timeout);

DESCRIPTION
       Pass a long as parameter containing timeout - the maximum time in
       milliseconds that you allow the libcurl transfer operation to take.

       See CURLOPT_TIMEOUT(3) for details.

DEFAULT
       0 (zero) which means it never times out during transfer.

           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

           /* complete within 20000 milliseconds */
           curl_easy_setopt(curl, CURLOPT_TIMEOUT_MS, 20000L);

           result = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }
