# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_REFERER, char **hdrp);

CURL handle.

CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
curl_easy_setopt(curl, CURLOPT_REFERER, "https://example.org/referrer");
res = curl_easy_perform(curl);
if(res == CURLE_OK) {
char *hdr = NULL;
curl_easy_getinfo(curl, CURLINFO_REFERER, &hdr);
if(hdr)
printf("Referrer header: %s\n", hdr);
}
curl_easy_cleanup(curl);
}
