CURLINFO_REFERER3
Get the used referrer request header
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 gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.
Protocols
HTTP(S)
Examples
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);
}
}
Return value
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
