Question

I need a program that polls a site every second and responds if the site doesnt respond in 15 seconds. I made the following hack from an example program. On a dry run, it printed 7 times in 15 seconds. Cant I make curl_easy_perform wait for 15 seconds before responding?

int main(void)
{
    CURL *curl;
CURLcode res;
char *postthis="moo mooo moo moo";

curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, "http://192.168.1.101");
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postthis);
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, (long)strlen(postthis));
curl_easy_setopt(curl, CURLOPT_TIMEOUT, 15);

while(1)
{
    Sleep(1000);
    res = curl_easy_perform(curl);
    if(res!= CURLE_OK)
        printf("nada \n");

}

Sleep(15000 - timeTakenForCurlInMs);
