	);

Function Description

Set a callback function for the given DHCPv6 options. This function will be called to pass option values from the server’s Advertise message to the user before the DHCPv6 client sends the first Request message to the server. This can be used to change configuration information before sending the Request message to the server. Calling this function will override any previous call. For example, you can register to receive a callback for the FQDN data from the server’s Advertise message. In your callback function, you can then change the FQDN data that will go out in the Request message with tfInterfaceSetOptions() (see the tfInterfaceSetOptions() section for more information). Note: There are no known circumstances in which this capability is currently required. This functionality is being included only as a precaution against hypothetical buggy servers and should be disregarded unless you have specific reasons to use it.
