# curl\_url\_dup(3)

duplicate a URL handle

## NAME

curl\_url\_dup - duplicate a URL handle

## SYNOPSIS

```
#include <curl/curl.h>
CURLU *curl_url_dup(const CURLU *inhandle);
```

## DESCRIPTION

Duplicates the URL object the input *CURLU* *inhandle* identifies and returns a pointer to the copy as a new *CURLU* handle. The new handle also needs to be freed with *[curl\_url\_cleanup(3)](/curl_url_cleanup/3.md)*.

## PROTOCOLS

## EXAMPLE

```
int main(void)
{
  CURLUcode rc;
  CURLU *url = curl_url();
  CURLU *url2;
  rc = curl_url_set(url, CURLUPART_URL, "https://example.com", 0);
  if(!rc) {
    url2 = curl_url_dup(url); /* clone it */
    curl_url_cleanup(url2);
  }
  curl_url_cleanup(url);
}
```

## AVAILABILITY

Added in curl 7.62.0

## RETURN VALUE

Returns a pointer to a new *CURLU* handle or NULL if out of memory or if *inhandle* is NULL.
