Get a simple HTTP page
This example just fetches the HTML from a given URL and sends it to stdout. Possibly the simplest libcurl program you can write.
By replacing the URL this will of course be able to get contents over other supported protocols as well.
Getting the output sent to stdout is a default behavior and usually not what you actually want. Most applications will instead install a write callback to have receive the data that arrives.
#include <stdio.h>
#include <curl/curl.h>
int main(void)
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "");
/* Perform the request, res will get the return code */
res = curl_easy_perform(curl);
/* Check for errors */
if(res != CURLE_OK)
fprintf(stderr, "curl_easy_perform() failed: %s\n",
/* always cleanup */
return 0;
