nng_url_clone - clone URL structure
== SYNOPSIS
[source, c]
----
#include <nng/nng.h>
int nng_url_clone(nng_url **dup, nng_url *orig);

using
xref:nng_url_free.3.adoc[`nng_url_free()`] when it is no longer needed.
== RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
== ERRORS
[horizontal]
`NNG_ENOMEM`:: Insufficient free memory exists to duplicate a message.
