# CURLINFO\_EFFECTIVE\_URL(3)

last used URL

## 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)](/CURLOPT_URL/3.md)*.

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)](/curl_easy_cleanup/3.md)* on the corresponding curl handle.

The returned string has limited life-time. It might get destroyed at the next libcurl function call involving this same *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: %s\n", url);
    }
    curl_easy_cleanup(curl);
  }
}
```

## AVAILABILITY

Added in curl 7.4

## RETURN VALUE

*[curl\_easy\_getinfo(3)](/curl_easy_getinfo/3.md)* returns a CURLcode indicating success or error.

CURLE\_OK (0) means everything was OK, non-zero means an error occurred, see *[libcurl-errors(3)](/libcurl-errors/3.md)*.
