# nng\_url\_clone(3)

clone URL structure

## NAME

nng\_url\_clone - clone URL structure

## SYNOPSIS

```
#include <nng/nng.h>
int nng_url_clone(nng_url **dup, nng_url *orig);
```

## DESCRIPTION

The `nng_url_clone()` makes a clone of the original URL structure *orig*, and saves the result in the location pointed by *dup*. This clone includes fully duplicating each of the member fields.

The new `nng_url` structure can be disposed of using `nng_url_free()` when it is no longer needed.

## RETURN VALUES

This function returns 0 on success, and non-zero otherwise.

## ERRORS

`NNG_ENOMEM`

Insufficient free memory exists to duplicate a message.
