CURLINFO_REFERER3

Usage

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

Overview

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

Examples

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

Return value

curl_easy_getinfo(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
