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. The memory gets freed
       automatically when you call curl_easy_cleanup(3) on the corresponding curl handle.

PROTOCOLS

       This functionality affects http only

EXAMPLE

       int main(void)
       {
         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);
         }
       }
