BlueJ,
I wanted to you, but could not find a single instance of msg in
your code snippet, let alone sendto(msg).

What's emalloc and bzero? What's key_list, Key, byte? Your code snippet
is incomplete at best. If you want , copy and paste a reduced source
that exhibits your problem but is still compilable, or at least contains
enough information for a human reader to understand.
