nng_msg_dup - duplicate a message
|
||
|
|
|
||
|
|
== SYNOPSIS
|
||
|
|
|
||
|
|
[source, c]
|
||
|
|
----
|
||
|
|
#include <nng/nng.h>
|
||

|
== DESCRIPTION
|
||
|
|
|
||
|
|
The `nng_msg_dup()` makes a duplicate of the original message _orig_, and
|
||
|
|
saves the result in the location pointed by _dup_.
|
||
|
|
The actual message body and header content is copied,
|
||
|
|
but the duplicate may contain a
|
||
|
|
different amount of unused space than the original message.
|
||
|
|
|
||
|
|
== RETURN VALUES
|
||
|
|
|
||
|
|
This function returns 0 on success, and non-zero otherwise.
