Can any one enlighten me on how announce() etc. can be used design an
echo server with UDP,
or point to samle code?
...
   char adir[40];
   int afd ;

   afd = announce("udp!*!1234", adir);

   and??
...

This works if you write "headers" to the control
file after the announce. Otherwise, you still need
to do the listen and accept. See ip(3) for more.
