       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REFERER, char *where);

DESCRIPTION

       this option.

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         /* tell it where we found the link to this place */
         curl_easy_setopt(curl, CURLOPT_REFERER, "https://example.com/aboutme.html");

         curl_easy_perform(curl);
       }
