NAME

       CURLINFO_REFERER - get the used referrer request header

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_REFERER, char **hdrp);

DESCRIPTION

       Pass in a pointer to a char pointer and get the referrer header used in the most recent request.

       The  hdrp  pointer  is  NULL  or points to private memory you MUST NOT free - it gets freed when you call
       curl_easy_cleanup(3) on the corresponding curl handle.

PROTOCOLS

           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)
