# NAME

# SYNOPSIS

~~~c

                          long speedtime);
~~~

~~~c
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    /* abort if slower than 30 bytes/sec during 60 seconds */
    curl_easy_setopt(curl, CURLOPT_LOW_SPEED_TIME, 60L);
    curl_easy_setopt(curl, CURLOPT_LOW_SPEED_LIMIT, 30L);
    result = curl_easy_perform(curl);
    if(result == CURLE_OPERATION_TIMEDOUT) {
      printf("Timeout.\n");
    }
    /* always cleanup */
    curl_easy_cleanup(curl);
