[En-Nut-Discussion] Destination unreachable ICMP Message for UDP sockets

[Ole Reinhardt]

Hi all,

I have an urgend project where I need a udp socket to be informed when I
get back a destination unreachable icmp message
(http://en.wikipedia.org/wiki/ICMP_Destination_Unreachable)

For TCP sockets NutOS implements the handling of this message, but for
UDP sockets an incomming destination unreachable icmp message is
ignored.

For TCP sockets the socket is aborted.

Has anyone just implemented this mechanism for UDP sockets too? I don't
even have a good idea _how_ to implement this behaviour for udp sockets
as these are datagram oriented and not stream oriendted sockets. So how
to inform the application that a just sended packet did not receive it's
recipient?

Any suggestions are wellcome!

Regards,

Ole Reinhardt
