CURLOPT_TIMEOUT_MS

CURLOPT_TIMEOUT_MS is one of the accepted parameters for curl_setopt parameter #2.

CURLOPT_TIMEOUT_MS — The maximum number of milliseconds to allow cURL functions to execute. If cURL is built to use the standard system name resolver, that portion of the connect will still use full-second resolution for timeouts with a minimum timeout allowed of one second. Defaults to 0, meaning that functions never time out during transfer. Available as of cURL 7.16.2.

CURLOPT_TIMEOUT_MS = 155;
