NAME

CURLINFO_EFFECTIVE_URL - last used URL

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_EFFECTIVE_URL, char **urlp);

DESCRIPTION

Pass in a pointer to a char pointer and get the last used effective URL.

In cases when you have asked libcurl to follow redirects, it may not be the same value you set with CURLOPT_URL(3).

The urlp pointer is NULL or points to private memory. You must not free it. It 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 result;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
    result = curl_easy_perform(curl);
    if(result == CURLE_OK) {
      char *url = NULL;
      curl_easy_getinfo(curl, CURLINFO_EFFECTIVE_URL, &url);
      if(url)
        printf("Redirect to: %sn", url);
    }
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in curl 7.4

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).
